āļŠāļāļ āļ.āļ. āļ āļēāļ āļ is one sitting carrying three papers, and a strong analytical score does nothing for you if English lands below half marks. We teach each paper to its own line, in the order that puts all three above it on the same day.
OCSC Part A is the general-ability paper the Office of the Civil Service Commission sets for most Thai government departments. One sitting covers analytical thinking, English, and civil service knowledge and ethics, and all three are passed separately. The pass certificate is what makes you eligible for a department's Part B and Part C.
Key Points
Most candidates are working while they prepare, so the format is chosen around a working week, and the paper being worked on decides how long a session needs to be.
Evening and weekend sessions at home, or somewhere quiet near your office. Tutor and candidate are paired by the rail line they already share, because a āļ āļēāļ āļ candidate is usually arriving straight from work.
The same coaching for candidates outside Greater Bangkok, and for anyone whose shift pattern makes a fixed weekly slot difficult.
For colleagues preparing for the same round. The law and ethics paper works well in a small group because the questions are situations, and a situation is worth arguing about.
You sit āļ āļēāļ āļ at the level of the qualification you register with, and that choice decides which round is open to you and where the analytical line sits. A certificate issued at a higher level may also be used to compete for a post at a lower one.

| Description | The paper round is the one that accepts every qualification level, and for āļāļ§āļ. holders it is usually the only one that opens. Building a plan around a round that may never open at your level is the quietest way to lose a year. | The paper is identical to the āļāļ§āļ. sitting and so are the three lines. What changes is the range of positions that will accept the certificate afterwards, which is worth checking against your target department before you choose the level you register at. | This is the level with the most candidates and the most competition for seats, and the level the e-Exam round is normally built around. Deciding between the two rounds matters most here, because e-Exam seats can be gone within days of the window opening. | The one level where a threshold moves. The analytical paper is judged at 65 percent here, which is five marks more out of a hundred than every other level, while English and the ethics paper stay where they are. A certificate earned at this level can be used to compete for bachelor's-level posts. |

The analytical paper holds three strands under one mark total. The English paper and the law and ethics paper each stand alone. Knowing which is which changes how the study weeks are spent.
The first three modules share a single 100-mark paper and a single 60 percent line, so a weak strand can be carried by the other two. The English paper and the law and ethics paper have no such cushion: each is scored alone, against its own line, on the same day.
The Thai-language strand inside the analytical paper. This is where the old standalone Thai paper went, which is why candidates working from older material think it disappeared.
Pattern work with no subject matter attached. Nothing here can be revised in the ordinary sense; what improves is the speed at which you recognise a rule you have met before.
Arithmetic under clock pressure, in the shapes an office produces: proportions, money, movement, and figures lifted off a table or a chart.
Fifty marks, judged at 50 percent, standing entirely on its own. The register is written correspondence and short factual passages, so conversational practice only takes you part of the way.
Fifty marks, judged at 60 percent, and the paper most often missing from a homemade study plan. Questions arrive as situations, so the answer is a principle applied, and the statute is what the principle came from.
A final-year student and a candidate resitting after one failed paper need opposite study plans, and the difference is visible in the first diagnostic.
You can sit Part A before any vacancy exists, and most people should. The certificate waits for the job advertisement rather than the other way round, and the analytical paper is easiest to prepare while you are still in the habit of studying.
Recommended:
This programme reports to the candidate, and the report is shaped like the exam: three papers, three lines, three separate answers to the question of whether you are ready.
Each session closes with your standing on the analytical paper, on English and on law and ethics, each against its own line. A combined score out of 200 is never quoted, because it cannot tell you whether you passed.
Inside the analytical paper, errors are split between language, abstract and quantitative, so you can see which strand is carrying the paper and which one is being carried.
Tense, article, preposition, vocabulary in context, inference. The same five headings every week, so a shrinking list is visible rather than asserted.
For every scenario answered wrongly, the note records which principle actually governed it and which one you reached for instead. That pairing is what stops the same mistake returning.
Registration windows and sitting dates for your chosen round are repeated at the foot of every note, because the deadline that gets missed is usually the registration one.
None of these are about effort. Each one is a candidate preparing carefully for something slightly different from the exam they will sit.
Challenge
Root cause
Free practice files still circulate with a standalone Thai-language paper, which is how āļ āļēāļ āļ used to be built. In the current form the Thai work sits inside the analytical paper as āļāļēāļĢāļāļīāļāļ§āļīāđāļāļĢāļēāļ°āļŦāđāđāļāļīāļāļ āļēāļĐāļē, and the paper that gets left out is āļāļ§āļēāļĄāļĢāļđāđāđāļĨāļ°āļĨāļąāļāļĐāļāļ°āļāļēāļĢāđāļāđāļāļāđāļēāļĢāļēāļāļāļēāļĢāļāļĩāđāļāļĩ: fifty marks with a sixty percent line of its own.
Edulom solution
Session one is a diagnostic against the three papers as they stand now. Whatever material you already own gets sorted into what still applies, what has moved inside another paper, and what was never on this blueprint.
Challenge
Root cause
Two hundred marks invites arithmetic. A candidate sees 132 and relaxes, while English sits at 24 out of 50, a single mark under its line. Nothing in the three thresholds is pooled, so a combined score is a number that cannot answer the only question that matters.
Edulom solution
Progress is tracked as three percentages against three lines. Any practice set that reports one score gets re-scored into three before we look at it together.
Challenge
Root cause
Fifty percent looks generous next to sixty, so English drifts to the end of the plan. It is also the paper where a thin base takes longest to move, because grammar, vocabulary and inference each need their own repetitions, and a final fortnight is too short for any of them.
Edulom solution
English starts in the first week and runs in short sessions throughout, with reading drawn from the written register the paper actually uses, and conversational material left aside.
Challenge
Root cause
Candidates arrive able to recite headings on good governance, administrative organisation and civil service ethics, then meet a question describing an official in a situation and asking what should happen. The paper tests which principle governs the case, and a heading recited from memory answers nothing.
Edulom solution
We teach it as scenarios. Each principle is met first as a case you have to decide, and the rule it comes from is attached afterwards, so it is retrieved by the situation that triggers it.
Challenge
Root cause
The e-Exam round attracts candidates because results return sooner, and in practice it opens for bachelor's and master's holders. Someone with a vocational certificate who holds out for it can watch the Paper & Pencil window close while waiting, and the next chance is a year away.
Edulom solution
The route is settled before registration opens, from the qualification you will register with and the season your target department usually advertises. Whichever route you take, the questions and the pass lines are the same.
Challenge
Root cause
OCSC states the Part A certificate stays usable unless āļ.āļ. rules otherwise, and a certificate issued at a higher level may be used to compete at a lower one. Candidates who passed years ago, or who passed at master's level and are now applying for a bachelor's-level post, book an exam they had already cleared.
Edulom solution
Before a study plan is written, we check what you hold, at which level, and whether it covers the post you are aiming at. A few candidates leave that first conversation with no exam to sit at all.
Five of these six cost a full year, because āļ āļēāļ āļ comes round once a cycle and a missed registration window cannot be reopened.
Every decision below comes from the same fact: āļ āļēāļ āļ is three exams wearing one name, and it is marked that way.
Sessions, mocks and notes all report three separate percentages. A candidate here never walks in believing a comfortable total means a pass, which is the single most common way a prepared person fails.
It is the newest paper and the one homemade plans skip. Fifty marks at a sixty percent line is a third of the sitting, and it is taught here as scenarios from the first week onward.
The deadline that ends most attempts is the registration window, not the exam. The route and the level are settled first, and the study weeks are fitted into what remains.
A replacement tutor, charged for nothing, when the pairing turns out wrong. A written note after every session. A figure you see in writing before any class is booked. Nobody here will promise you a pass.
There are no tutor profiles on this page, and there will not be until someone in Thailand has actually been taught here. What follows is the bar a āļ āļēāļ āļ tutor clears before meeting a candidate.
Online sessions carry the whole programme, which matters for this subject because candidates are often already posted outside the capital, or working shifts that will not hold a fixed weekday slot.
In person, pairing starts from the rail line. A candidate who clocks off at six has one usable hour that evening, and the journey decides whether it survives. Coverage is still being built, so no district list is published here yet.
The questions candidates ask in a first call, in the order they usually ask them.
āļŠāļģāļāļąāļāļāļēāļ āļ.āļ. runs āļ āļēāļ āļ, the general-ability stage, for most government departments. Passing it does not place you in a job; it makes you eligible to sit the stages that do. āļ āļēāļ āļ tests the knowledge a specific position needs, and āļ āļēāļ āļ assesses suitability and is usually an interview. Both belong to the department advertising the vacancy, and both run on that department's own calendar.
This matters at the planning stage. A candidate who assumes one exam leads straight to a posting will be caught out by the gap between passing Part A and the day a suitable vacancy is advertised, which can be months. A candidate who understands the sequence sits Part A early, holds the certificate, and waits with it in hand.
One more boundary is worth learning before you register. Several career paths run a Part A of their own and do not accept the OCSC one: teaching posts, the police, the armed forces, prosecutors, judges, and local government staff. If your target is in that list, the exam you need is a different exam.
Practical Tips
The sitting carries 200 marks across 100 questions. Analytical thinking takes 100 of those marks, English 50, and public service law and ethics 50. Each of the three has a pass line of its own, and they are not pooled: 60 percent on analytical thinking, 50 percent on English, 60 percent on law and ethics. Sit at master's level and the analytical line moves to 65 percent, while the other two stay put.
Inside the analytical paper there are three strands sharing one mark total: language, abstract reasoning and quantitative reasoning. Because they share the total and the line, a weak strand can be carried by the other two, which is a genuine strategic option. The English paper and the law paper offer no such trade, each being scored alone.
That asymmetry is the whole shape of a study plan. Effort on the analytical paper can be moved between strands to wherever it buys the most marks. Effort on the other two papers cannot be moved anywhere, because each has to clear its own line on the day.
Mistakes & Solutions
Both routes lead to the same paper. Structure, content and pass criteria are identical, so this is a logistics decision and should be made as one.
The e-Exam round is sat on a computer, registers earlier in the year, and runs across several sittings, with results released in waves after each. Its seat pool is the smaller of the two and closes quickly once the window opens. In practice it opens for bachelor's and master's holders, which settles the question for anyone registering with a āļāļ§āļ. or āļāļ§āļŠ. qualification.
The Paper & Pencil round accepts every qualification level, offers a far larger seat pool, and concentrates on a single nationwide date, with results following some months later. For candidates who need a certificate in hand by a particular month, that lag is the thing to plan around, and it is the reason the route should be chosen before the calendar year starts rather than after a window has already opened.
Practical Tips
The pass certificate is printed from the OCSC job portal once results are published. OCSC states that it remains usable unless āļ.āļ. rules otherwise, so there is no expiry date to diary and no reason to re-sit out of caution. A certificate issued at a higher qualification level may also be used to compete for a position at a lower one, which means a master's-level pass covers bachelor's-level applications.
Those two rules together retire a surprising number of planned sittings. Before booking anything, check whether you already passed in an earlier year, and check the level it was issued at against the level your target post requires. Some candidates arrive at a first session expecting a six-month plan and leave with a printed certificate instead.
If a paper did fall below its line, the sitting fails as a whole and all three are taken again. The work that follows is uneven by design: the failed paper is rebuilt from its foundations, while the two that passed are held in place with short weekly sets, which is enough to keep them above the line without consuming weeks that the failed paper needs.
The first session is a diagnostic across all three, scored the way the exam scores them. You leave it knowing your three percentages, which round to register for, and whether you need to sit at all.
