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.
Recommended 6-Week Study Plan
Week-by-Week Breakdown
| Week | Focus | Daily Time | Activities |
|---|---|---|---|
| 1 | Diagnostic + Math Foundations | 1-2 hrs | Take a practice OAR, review arithmetic and algebra basics |
| 2 | Math Skills Deep Dive | 1-2 hrs | Geometry, word problems, no-calculator drills |
| 3 | Reading Comprehension | 1-2 hrs | Passage strategies, inference practice, timed sets |
| 4 | Mechanical Comprehension | 1-2 hrs | Physics concepts, simple machines, fluid dynamics |
| 5 | Mechanical + Mixed Practice | 1-2 hrs | Gears/pulleys, electricity, full mixed sets |
| 6 | Full Practice Tests + Review | 1-2 hrs | Timed full-length practice, weak-area review |
Study Priority by Subtest
| Subtest | Questions | Time | Seconds/Question | Study Priority |
|---|---|---|---|---|
| MST | 30 | 40 min | ~80 sec | High — broadest content coverage |
| RCT | 20 | 30 min | ~90 sec | Medium — strategy over memorization |
| MCT | 30 | 15 min | ~30 sec | High — 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
| Technique | Example |
|---|---|
| Break apart multiplication | 17 x 6 = (10 x 6) + (7 x 6) = 60 + 42 = 102 |
| Use fractions for percentages | 25% of 80 = 1/4 of 80 = 20 |
| Round and adjust | 49 x 8 = 50 x 8 - 8 = 400 - 8 = 392 |
| Cross-multiply for proportions | 3/4 = 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
| Strategy | Why It Matters |
|---|---|
| Answer every question | Unanswered questions count against you |
| Do not rush early questions | Early CAT questions carry more weight |
| Do not panic at hard questions | Harder questions often mean you are doing well |
| Track time loosely | Glance at the clock every 5-10 questions |
| Eliminate obvious wrong answers | Even partial elimination improves guessing accuracy |
| Trust your preparation | Second-guessing wastes time on adaptive tests |
Time Management by Subtest
| Subtest | Total Time | Questions | Target Pace | Warning Flag |
|---|---|---|---|---|
| MST | 40 min | 30 | ~1 min 20 sec each | If stuck > 2 min, make best guess and move on |
| RCT | 30 min | 20 | ~1 min 30 sec each | If stuck > 2 min on a passage, commit to best answer |
| MCT | 15 min | 30 | ~30 sec each | If unsure, eliminate and guess immediately |
Common Mistakes to Avoid
| Mistake | Better Approach |
|---|---|
| Studying only your strongest area | Prioritize your weakest subtest |
| Using a calculator during practice | Practice without a calculator from day one |
| Taking the test before you are ready | Wait until practice scores consistently hit your target |
| Retaking without substantial improvement | Only retake if you identify specific fixable weaknesses |
| Cramming the night before | Review lightly, then rest |
| Skipping practice tests | Take at least 2-3 full timed practice tests before test day |
Which OAR subtest has the fastest required pace at approximately 30 seconds per question?
Math Skills Test
Reading Comprehension Test
Mechanical Comprehension Test
All subtests have the same pace
On a computer-adaptive test like the OAR, what does it typically mean when the questions feel increasingly difficult?
The test is malfunctioning
You are running out of time
You are likely answering correctly and the algorithm is increasing difficulty
You selected the wrong test version
What is the recommended approach when you are stuck on an OAR question for more than 2 minutes?
Leave it blank and move on
Spend another 2 minutes to make sure you get it right
Eliminate what you can, make your best guess, and move on
Go back to the previous question instead
