Polstat STIS study plan

Polstat STIS · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Matematika

  • Diagnose baseline Matematika ability by completing a timed 40-question mixed set (arithmetic, algebra, geometry, statistics) and logging accuracy per subtopic.

  • Master number properties and operations: fractions, decimals, percentages, ratio and proportion, and order-of-operations shortcuts, solving 30 drill problems without a calculator.

  • Build a personal formula sheet covering percentage change, ratio splitting, and averages, and recite each formula from memory in a self-quiz.

  • Establish a daily 45-minute study block and a mistake log that records every wrong answer with its cause (concept, careless, time).

Your checkpoint

A baseline score report plus a categorized mistake log with at least 40 entries and a one-page formula sheet.

Week 2

Matematika

  • Solve linear equations, inequalities, and two-variable systems, completing 25 problems with at least 80% accuracy.

  • Apply algebra to word problems (age, work-rate, mixture, and distance-speed-time) by translating 20 narratives into equations before solving.

  • Drill exponent and radical rules plus quadratic factoring, checking each answer by substitution.

  • Reduce average solving time per algebra item to under 90 seconds while holding accuracy above 75%.

Your checkpoint

A timed 30-question algebra set scored and reviewed, with time-per-item recorded.

Week 3

Matematika

  • Compute perimeter, area, and volume for triangles, circles, cylinders, and composite figures across 25 geometry problems.

  • Apply the Pythagorean theorem, similarity ratios, and angle relationships to solve 15 figure-based items without a diagram dependency.

  • Interpret tables, bar charts, line graphs, and pie charts by extracting two derived values from each of 10 data displays.

  • Memorize and apply mean, median, mode, range, and standard deviation concepts to 15 statistics questions.

Your checkpoint

A geometry-and-data quiz of 30 items completed under a 45-minute limit, with a written correction for every error.

Week 4

Matematika & Psikotes

  • Complete a full-length timed Matematika simulation and score each subtopic separately to identify the two weakest areas.

  • Drill number-series and arithmetic-logic patterns, solving 40 sequence items and writing the rule used for each.

  • Practice comparison-style quantitative reasoning (which quantity is larger) on 20 paired-quantity items under time pressure.

  • Review the mistake log and re-solve every previously missed problem type until each is correct twice in a row.

Your checkpoint

A full simulation score report with subtopic breakdown and a re-test on the two weakest subtopics scoring at least 80%.

Week 5

Psikotes

  • Solve verbal analogies and synonym-antonim items across 40 questions, articulating the relationship type (cause, part-whole, function) for each.

  • Complete 30 syllogism and logical-deduction problems, diagramming premises before selecting a conclusion.

  • Practice spatial and figural reasoning (rotation, folding, pattern completion) on 25 items using a self-drawn sketch method.

  • Build speed on numerical psychotest items by finishing 30 quick-calculation questions in 15 minutes.

Your checkpoint

A psychotest practice log of 125 solved items with accuracy rate and average time per item per category.

Week 6

Psikotes & Wawancara

  • Run two full-length timed Psikotes simulations and compare category scores to the week-5 log to confirm improvement.

  • Draft and rehearse answers to 10 core interview questions (motivation, strengths, weaknesses, teamwork, conflict, failure, why Polstat STIS).

  • Record three mock interview answers and review them for structure (situation-action-result), filler words, and length.

  • Research the Polstat STIS program, curriculum, and career paths, and write a 150-word answer to 'Why this program and this institution?'

  • Prepare a concise personal introduction (60-90 seconds) that links academic background, data interest, and goals.

Your checkpoint

A two-page interview answer bank plus three recorded mock answers with a written self-critique of each.

Week 7

Matematika & Wawancara

  • Run one mixed simulation covering Matematika and Psikotes back-to-back to build stamina across a 2-hour session.

  • Conduct a live mock interview with a peer or mentor and collect feedback on at least five behavioral questions.

  • Refine weak interview answers using the feedback and rehearse them aloud until delivery is fluent without notes.

  • Re-drill the three lowest-accuracy Matematika subtopics from the week-4 report with 20 targeted problems each.

Your checkpoint

A mock-interview feedback sheet with five rated answers and a revised answer bank.

Week 8

Matematika & Psikotes & Wawancara

  • Take two full-length timed simulations under exam conditions and target at least 75% overall on the second attempt.

  • Review every remaining mistake-log entry and confirm each is resolved with a correct re-solve.

  • Rehearse the full interview set aloud twice, timing each answer to stay within 2 minutes.

  • Finalize logistics: confirm test format, allowed tools, and a rest-and-sleep schedule for exam week.

Your checkpoint

A final readiness report showing simulation scores, resolved mistake count, and a signed exam-day checklist.

Milestones

Week 4: Achieve at least 70% on the full Matematika simulation and show that the two weakest subtopics have been re-tested at 80% or higher.

Week 6: Show measurable improvement in Psikotes category scores versus the week-5 log and complete a first-draft interview answer bank covering at least 10 questions.

Week 8: Score at least 75% on the final full-length simulation, confirm all mistake-log entries are resolved, and deliver a completed exam-day checklist.
