Studying for SKD CPNS from scratch effectively starts by mapping the three subtests: drill TIU early because it relies on accumulated pattern recognition, practice TKP daily because it carries the largest share of the score, and memorize TWK in stages because it is dense recall. Learn the official passing grades first, then build a study schedule backward from the expected selection date.
- SKD has 110 questions: 30 TWK, 35 TIU, 45 TKP, completed in 100 minutes
- Official 2024 general-formation passing grades: TWK 65, TIU 80, TKP 166
- Clearing the passing grade alone is not enough; you must also rank within 3 times the number of positions
- Question banks for each subtest: TWK, TIU, and TKP
- A weakness notebook to log the question types you keep missing
- A CAT-style simulation or tryout app with a timer and automatic scoring
Key Numbers to Memorize Before You Start
Passing Grade and Character of Each SKD Subtest
| Subtest | General Passing Grade | Primary Study Method |
|---|---|---|
| TWK (30 questions) | 65 | Staged recall: Pancasila, constitution, history, state defense |
| TIU (35 questions) | 80 | Repeated pattern drills: numerical, verbal, logic |
| TKP (45 questions) | 166 | Understanding work values: choose the option scored 5 |
TWK and TIU award 5 for a correct answer and 0 for a wrong or blank one. TKP scores every option from 1 to 5, so no answer is truly zero as long as you choose one.
Understand the Scoring Before You Build a Study Strategy
Many beginners answer all three subtests the same way, yet their scoring logic differs. In TIU and TWK, a wrong answer is worth the same as a blank, which is zero, so guessing a hard question in the final seconds is always worth trying with no penalty. In TKP, every option carries a score from 1 to 5 and your task is to pick the one closest to the ideal behavior of a civil servant, which makes TKP more like a personality quiz with a hidden key than a right-or-wrong test. The implication for study is clear. TIU is drilled for speed and accuracy. TWK is studied for broad coverage of recall. TKP is practiced so you grow used to reading situational statements and recognizing the most professionally mature response. These three domains demand different practice methods, and treating them as one wastes your study time.
6 Steps to Study for SKD CPNS from Scratch
This framework assumes a 4-month runway. If you only have 2 months, merge the first two steps and increase tryout volume in the final month.
- 1
Week one: a diagnostic tryout to map your weak spots
Start with one full timed tryout covering TWK, TIU, and TKP at once. The goal is not a high score but seeing which subtest sits furthest from its passing grade. Record your score per subtest and, more importantly, the question types you repeatedly miss. This diagnostic determines how you split your study time, because applicants from engineering backgrounds tend to be strong in numerical TIU yet weak in TWK, while social-science graduates often show the reverse. Without this map, you risk spending time on material you have already mastered.
Tips- Do the diagnostic on a computer to get used to reading questions on screen like the CAT system
- Keep this first score sheet as a baseline to measure progress each month

Month one: build a TIU foundation because its learning curve is the longest
TIU measures numerical, verbal, and logical ability built through repeated practice, so it climbs slowest and deserves to be started first. For numerical, restore basic arithmetic, number series, ratios, and simple word problems before touching mixed sets. For verbal, drill synonyms, antonyms, analogies, and syllogisms until the patterns feel automatic. In this phase chase accuracy first: work without a timer until your correct rate passes 80 percent, then add the timer. TIU is the one subtest that resists memorization, so consistent daily practice of 4 to 5 sessions per week matters far more than occasional marathon study.
Tips- Practice one question type at a time first, then mix them, so you recognize each pattern
- For series and logic, write out your reasoning so errors are easy to trace
- 3
Month two: drill TKP daily because it carries the heaviest weight
TKP contributes a maximum of 225 points, the largest share of the 550 total, so it deserves near-daily practice. Unlike other subtests, TKP rests on understanding a civil servant's ideal behavior with no memorized formulas: public service, integrity, teamwork, professional networking, social and cultural awareness, professionalism, and use of information technology. The practice is reading hundreds of situational statements and getting used to recognizing the answer scored 5, the response that solves the problem independently, prioritizes the organization, and keeps to ethics. The key in TKP is consistently choosing the most mature stance. The answer that sounds most heroic or most perfect often scores lower.
Tips- For every missed question, read why the other options scored lower
- Avoid extreme answers that dump the problem on a superior or refuse responsibility
TKP has a high threshold of 166 out of 225 and most often trips up candidates who underestimate it, even though it requires no formula at all. - 4
Months two to three: memorize TWK on a steady schedule
TWK is dense recall: Pancasila, the 1945 Constitution, national unity, the history of the national struggle, and state-defense awareness. This much material fails when crammed, so build it in short but regular sessions, for example one theme per session while immediately answering its questions. Study the modern question pattern, which often asks how a value applies in a real situation beyond rote articles. Because TWK has only 30 questions with a threshold of 65, the realistic target is mastering the most frequently appearing themes, then making sure you never lose points on basic questions that should be easy.
Tips- Make short flashcards for the dates, figures, and articles that recur often
- Review old material every week with spaced recall so you do not forget quickly
- 5
Month three: combine all three subtests in regular timed tryouts
Once each subtest's foundation is set, switch to combined tryouts that mimic the real conditions: 110 questions in 100 minutes, answered on a computer with no break. The biggest SKD challenge lies in time management across subtests, as demanding as the content itself, because 100 minutes for 110 questions averages under one minute per question. Train your rhythm: skip time-consuming numerical items, lock in the relatively quick TKP first, then return to the hard questions in the time left. Run a full tryout at least once a week, then dissect every mistake so the same pattern does not recur.
Tips- Use a skip-the-hard-first strategy so no easy question is lost to running out of time
- Note how many questions you left blank at the end; that number shows how good your time management is

Final month: stabilize your score and calibrate targets to the ranking system
The final month is for cementing scores above the passing grade with a safe margin, prioritizing consistency over an occasional record. Aim for TWK steady above 80, TIU above 90, and TKP above 175, all comfortably clear of the official thresholds. What sets careful candidates apart is grasping the ranking system: clearing the passing grade only qualifies you, while those who advance to SKB are the highest scorers up to 3 times the number of positions. So calibrate your target to the competitiveness of the formation you want, and choose a formation with a healthier applicant ratio if your practice scores still sit thin against the requirement.
Tips- A score stable across three tryouts is more convincing than one lucky high score
- Check applicant counts per formation on the SSCASN portal before locking your choice
Do not set your target exactly at the passing grade. In a competitive formation, a borderline score can still lose on ranking and fail before SKB.
Tailor Your Study to Your Background
Science and Engineering Graduates
Usually strong in numerical TIU. Shift study time toward TWK and verbal practice so you do not lose points on the subtests that feel unfamiliar.
Social Science and Humanities Graduates
Often comfortable with TWK and verbal items. Add numerical and logical TIU practice from month one because its learning curve is long.
Working Candidates with Limited Time
Use a dense 2-month framework: 60 minutes per night alternating TKP and TIU, plus one full tryout each weekend.
“Candidates who fail the SKD rarely fail because they are not smart. They fail because they split study time evenly, while TKP, the heaviest-weighted subtest, gets underestimated most. Once we start from a diagnostic and give time according to each candidate's weakness, their scores rise fastest in the very subtest they used to avoid.”
Readiness Checklist Before SKD Test Day
- Tryout score stable above the passing grade three times in a row
- Comfortable answering 110 questions in 100 minutes on a computer
- A clear strategy to skip hard questions and return in the time left
- Understanding the 3-times-formation ranking system as the real cutoff above the passing grade
- Already checked applicant counts for your chosen formation on the SSCASN portal
- Documents and exam card printed, test location confirmed
- The SKD has 110 questions (30 TWK, 35 TIU, 45 TKP) in 100 minutes, a maximum of 550, and 2024 general passing grades of TWK 65, TIU 80, TKP 166.
- The efficient study order: TIU first because its learning curve is longest, TKP daily because it carries the most weight, TWK in stages because it is dense recall.
- TWK and TIU award 5 for correct and 0 for wrong with no penalty, while TKP scores 1 to 5, so the task is choosing the most mature response.
- Clearing the passing grade is only the first requirement; those who advance to SKB are the highest scorers up to 3 times the number of positions, so aim for a safe margin.
