Mixed Set
Learn
Mixed practice sets are the final stage of an effective review cycle. Unlike topic-focused drills, mixed sets force you to identify question types and switch strategies rapidly - just like on the real test.
Why Mixed Practice Matters
- Context Switching: Trains your brain to shift between algebra, geometry, and data analysis
- Pattern Recognition: Develops ability to quickly identify question types
- Test Simulation: Mirrors the actual SAT/ACT experience
- Interleaving Effect: Research shows mixed practice improves long-term retention
Building Effective Mixed Sets
| Set Type | Questions | Time | Purpose |
|---|---|---|---|
| Mini Mixed | 10 | 12 min | Daily warm-up |
| Standard Mixed | 20 | 25 min | Regular practice |
| Weakness Focus | 15 | 20 min | 70% weak areas, 30% strong |
| Full Section | 38-60 | 55-60 min | Test simulation |
The Complete Review Cycle
- Identify weaknesses from recent practice (Lesson 1)
- Reinforce concepts through focused study (Lesson 2)
- Categorize question types you'll encounter (Lesson 3)
- Do timed drills on specific categories (Lesson 4)
- Analyze mistakes and log errors (Lesson 5)
- Mixed practice to integrate everything (This lesson)
- Repeat the cycle every 1-2 weeks
Examples
Example: Creating a Weakness-Focus Mixed Set
Student's weak areas: Quadratics (30% correct), Percentages (50% correct)
Student's strong areas: Linear equations (85% correct), Basic geometry (80% correct)
Set composition for 15 questions:
- 5 quadratic questions (weakness)
- 4 percentage questions (weakness)
- 3 linear equation questions (maintenance)
- 3 geometry questions (maintenance)
Example: Mixed Set Strategy During the Test
First Pass (40% of time):
- Do all questions you immediately recognize
- Mark uncertain ones with a star
- Skip anything that looks like it needs more than 90 seconds
Second Pass (40% of time):
- Return to starred questions
- Work through medium-difficulty items
- Make educated guesses on very hard ones
Final Pass (20% of time):
- Check answers if time permits
- Ensure all questions are answered (no penalty for guessing)

10. [Exponents] Simplify: (2^3)(2^4)
A) 2^7 B) 2^12 C) 4^7 D) 4^12
Answer Key
1-B (8x-14 = 2(4x-7) = 2(13) = 26)
2-A (side = 9, area = 81)
3-B (5 x 84 = 420, 420 - 338 = 82)
4-B (60 x 0.70 = 42)
5-A (factors to (x-2)(x-3) = 0)
6-B (3/8 x 40 = 15)
7-A (2(4) - 3 = 5)
8-B (radius = 5, area = 25pi)
9-C (when x=0: -2y=12, y=-6)
10-A (add exponents: 3+4=7)
