Study Plan and Test-Day Strategy

Key Takeaways

  • A 4-6 week study plan with 1-2 hours daily covers all three subtests thoroughly.
  • Prioritize your weakest subtest first — most candidates struggle most with Mechanical Comprehension.
  • Practice without a calculator from day one to build mental math fluency.
  • On test day, manage your time by subtest: MST gets 80 seconds per question, RCT gets 90 seconds, MCT gets only 30 seconds.
  • The adaptive format means harder questions indicate better performance — do not panic when difficulty increases.

Study Plan and Test-Day Strategy

Recommended 6-Week Study Plan

Week-by-Week Breakdown

WeekFocusDaily TimeActivities
1Diagnostic + Math Foundations1-2 hrsTake a practice OAR, review arithmetic and algebra basics
2Math Skills Deep Dive1-2 hrsGeometry, word problems, no-calculator drills
3Reading Comprehension1-2 hrsPassage strategies, inference practice, timed sets
4Mechanical Comprehension1-2 hrsPhysics concepts, simple machines, fluid dynamics
5Mechanical + Mixed Practice1-2 hrsGears/pulleys, electricity, full mixed sets
6Full Practice Tests + Review1-2 hrsTimed full-length practice, weak-area review

Study Priority by Subtest

SubtestQuestionsTimeSeconds/QuestionStudy Priority
MST3040 min~80 secHigh — broadest content coverage
RCT2030 min~90 secMedium — strategy over memorization
MCT3015 min~30 secHigh — fastest pace, least intuitive for many

The Mechanical Comprehension Test is the most time-pressured section at only 30 seconds per question. Many candidates find it the hardest because it tests applied physics concepts that require both knowledge and speed.

No-Calculator Math Practice

Since the OAR does not allow a calculator, build these skills early:

Mental Math Shortcuts

TechniqueExample
Break apart multiplication17 x 6 = (10 x 6) + (7 x 6) = 60 + 42 = 102
Use fractions for percentages25% of 80 = 1/4 of 80 = 20
Round and adjust49 x 8 = 50 x 8 - 8 = 400 - 8 = 392
Cross-multiply for proportions3/4 = x/20 → 3 x 20 = 4x → x = 15
Estimate square roots√50 ≈ 7.07 (between √49 = 7 and √64 = 8)

Practice these techniques until they become automatic. Every second saved on arithmetic is a second available for problem-solving.

Test-Day Checklist

Before the Test

  • Get 7-8 hours of sleep the night before
  • Eat a balanced breakfast (protein + complex carbs)
  • Bring valid government-issued photo ID
  • Arrive 30 minutes early
  • Leave your phone, calculator, and study materials in the car
  • Use the restroom before entering the testing room

During the Test

StrategyWhy It Matters
Answer every questionUnanswered questions count against you
Do not rush early questionsEarly CAT questions carry more weight
Do not panic at hard questionsHarder questions often mean you are doing well
Track time looselyGlance at the clock every 5-10 questions
Eliminate obvious wrong answersEven partial elimination improves guessing accuracy
Trust your preparationSecond-guessing wastes time on adaptive tests

Time Management by Subtest

SubtestTotal TimeQuestionsTarget PaceWarning Flag
MST40 min30~1 min 20 sec eachIf stuck > 2 min, make best guess and move on
RCT30 min20~1 min 30 sec eachIf stuck > 2 min on a passage, commit to best answer
MCT15 min30~30 sec eachIf unsure, eliminate and guess immediately

Common Mistakes to Avoid

MistakeBetter Approach
Studying only your strongest areaPrioritize your weakest subtest
Using a calculator during practicePractice without a calculator from day one
Taking the test before you are readyWait until practice scores consistently hit your target
Retaking without substantial improvementOnly retake if you identify specific fixable weaknesses
Cramming the night beforeReview lightly, then rest
Skipping practice testsTake at least 2-3 full timed practice tests before test day
