Timed Drill
Learn
Timed drills are essential for building the speed and accuracy needed for SAT/ACT success. This lesson teaches you how to structure effective timed practice sessions as part of your review cycle.
Time Benchmarks
| Test Section | Questions | Time | Per Question |
|---|---|---|---|
| SAT Math (No Calculator) | 20 | 25 min | ~75 sec |
| SAT Math (Calculator) | 38 | 55 min | ~87 sec |
| ACT Math | 60 | 60 min | 60 sec |
Timed Drill Strategies
- Progressive Timing: Start at 2x the target time, gradually decrease
- Category Focus: Drill one question type at a time initially
- Skip and Return: Practice marking hard questions and returning
- Two-Pass Method: First pass for questions you know, second for harder ones
Building Speed Without Sacrificing Accuracy
- Master the concept first (untimed)
- Practice with generous time limits
- Gradually reduce time as accuracy improves
- Target 85% accuracy before reducing time further
- Track both time AND accuracy in your error log
Examples
Example Timed Drill Session (15 minutes)
Setup: 10 algebra questions, 90 seconds each
- Set timer for 15 minutes total
- Work through questions in order
- Mark any you skip with a star
- After first pass, return to starred questions
- When timer ends, circle where you stopped
- Finish remaining questions (no time pressure) in different color
- Grade and analyze: timed vs. untimed accuracy
Example: Progressive Time Reduction
Week 1: 10 questions in 20 minutes (2 min each)
Week 2: 10 questions in 15 minutes (90 sec each)
Week 3: 10 questions in 12 minutes (72 sec each)
Week 4: 10 questions in 10 minutes (60 sec each) - ACT pace
