ก.พ. ภาค ก. Ready Review: OCSC Part A Exam Prep App for iPhone
Anyone planning a career in the Thai civil service has to clear the same first hurdle: the general knowledge and aptitude test from the Office of the Civil Service Commission, better known as the OCSC Part A exam (ก.พ. ภาค ก.). It tests analytical reasoning, Thai language and English in a single sitting, and most candidates struggle less with finding material than with knowing how ready they actually are.
This review looks at ก.พ. ภาค ก. Ready, an iPhone and iPad app from ChatStick Company Limited that brings more than 286 original practice questions, timed mock exams and a per-subject readiness score together in one place. Here is what it offers and who it suits.
What is ก.พ. ภาค ก. Ready?
ก.พ. ภาค ก. Ready is a study app built specifically for Thai candidates preparing for the OCSC Part A test. The entire interface is in Thai, written in a tone aimed at adults preparing for government jobs. Rather than being only a question bank, it combines practice questions with a readiness tracker, mock exams that return a pass or fail result, and habit tools that keep daily practice on track.
It works fully offline, requires no account or sign-up, and keeps all of your practice data on your own device.
All three Part A subjects covered
Subject | What you practice |
Analytical reasoning | Inference, logic, analogies, number series, applied math problems and reading tables and charts |
Thai language | Sentence ordering, word completion, reading for main ideas and summarizing |
English | Grammar, conversation, vocabulary and reading |
Every question comes with an explanation in Thai that tells you why the answer is correct, not just which option to pick. That makes it easier to understand the underlying approach and apply it to new questions.
Key features for OCSC exam prep
286+ original questions: across analytical reasoning, Thai and English
Real-time readiness score: shown as an honest score range, with per-subject rings that reveal strengths and weak spots at a glance
32+ timed mock exams: both short sets and full-length tests
26+ formulas and techniques: math shortcuts, quick-thinking tricks and option-elimination methods to help you finish on time
Mistake notebook: brings back questions you got wrong until you master them
Spaced-repetition vocabulary: 60+ English words reviewed on a spaced schedule
Motivation tools: daily goals, practice streaks, levels, XP and achievements, plus progress charts and weak-area suggestions
Mock exams with a pass or fail result
The timed mock exams are the most useful part for candidates close to test day. After each one, the app gives a pass or fail summary based on the official-style criteria of at least 60% overall and at least 50% in English, with a separate score for each subject so you know what to work on next. The criteria can be adjusted, and every result is clearly labelled as an informal assessment for practice.
How to get the most out of the app
Start by practicing all three subjects to get a baseline readiness score.
Check the per-subject rings and focus first on your lowest-scoring subject.
Read the formulas and techniques section before reasoning practice to speed up your solving.
Revisit the mistake notebook regularly and keep up with the English vocabulary reviews.
Take a timed mock exam and compare your results on the progress chart each week.
Tip: set a realistic daily goal in the app and protect your streak. Consistent daily practice usually does more than cramming in the last few days before the exam.
