Post-Test Analysis
📖 Learn
Taking a practice test is only half the work—the real learning happens during post-test analysis. This systematic review process turns every mistake into a learning opportunity and creates a roadmap for improvement.
The Value of Post-Test Analysis
Post-test analysis is the structured review of your practice test results to identify patterns, diagnose weaknesses, and create actionable study plans. Without proper analysis, you'll repeat the same mistakes. With it, every practice test makes you significantly better prepared for the next one.
The Post-Test Analysis Process
| Step | What to Do | Time Needed |
|---|---|---|
| 1. Score | Calculate your raw and scaled scores per section | 15-20 min |
| 2. Review ALL | Go through every question (not just wrong ones) | 60-90 min |
| 3. Categorize | Sort errors by type and topic | 20-30 min |
| 4. Analyze | Identify patterns and root causes | 15-20 min |
| 5. Plan | Create specific action items for improvement | 10-15 min |
Step 1: Score Your Test
- Count correct answers for each section (raw score)
- Use the test's score conversion table to get scaled scores
- Record scores for comparison with future tests
- Note: Different tests have different curves—don't compare raw scores across tests
Step 2: Review Every Question
Why Review Correct Answers Too?
- Lucky guesses: You might have guessed correctly without understanding
- Efficient methods: There might be a faster way to solve it
- Reinforcement: Reviewing correct reasoning strengthens that knowledge
- Pattern recognition: Seeing many examples helps you recognize question types
Step 3: Categorize Your Errors
| Error Type | Definition | Example |
|---|---|---|
| Content Gap | Didn't know the concept, rule, or formula | Didn't know the quadratic formula |
| Careless Error | Knew how to solve but made an avoidable mistake | Misread "at least" as "at most" |
| Time/Pacing | Ran out of time or rushed | Guessed on last 5 questions |
| Strategy Error | Used wrong approach or inefficient method | Solved algebraically when backsolving was faster |
| Trap Answer | Fell for a deliberately tempting wrong choice | Chose a too-extreme answer on reading |
Step 4: Analyze Patterns
Questions to Ask During Analysis
- Which topics appear most frequently in my errors?
- Are my errors concentrated in certain sections or spread out?
- Did I run out of time? On which section?
- Are errors mostly content gaps or careless mistakes?
- How do early-section errors compare to late-section errors (stamina)?
- Which question types or formats do I struggle with?
- Did I second-guess correct answers and change them to wrong ones?
Step 5: Create an Action Plan
- For content gaps: Schedule study time for specific topics
- For careless errors: Develop checking routines; slow down on easy questions
- For pacing issues: Practice timed sections; develop question triage strategy
- For strategy errors: Review strategy lessons; practice recognizing when to use each approach
- For trap answers: Study common trap patterns; practice process of elimination
The Error Log
What to Record
Keep a running log across all practice tests with these columns:
- Date and test name
- Section and question number
- Topic/concept tested
- Error type (content, careless, timing, strategy, trap)
- Brief description of what went wrong
- What you should do differently next time
Tracking Progress Over Time
| What to Track | Why It Matters |
|---|---|
| Overall scores by test date | Shows whether you're improving overall |
| Section scores over time | Reveals which areas are improving and which aren't |
| Error types over time | Shows if careless errors are decreasing, content gaps are closing |
| Errors by topic | Identifies persistent weaknesses that need more attention |
| Early vs. late section performance | Indicates whether stamina is improving |
💡 Examples
See post-test analysis in action.
Example 1: Categorizing Math Errors
Scenario: A student missed 8 questions on an SAT Math section. Here's the analysis:
| Q# | Topic | What Happened | Error Type |
|---|---|---|---|
| 5 | Linear equations | Made a sign error: -3 instead of +3 | Careless |
| 12 | Quadratic word problem | Didn't know how to set up the equation | Content gap |
| 15 | Systems | Could solve but took too long; guessed | Timing |
| 18 | Percent change | Calculated change from wrong base | Careless |
| 22 | Functions | Didn't understand function notation f(g(x)) | Content gap |
| 25 | Data analysis | Chose answer that was "close" without checking | Careless |
| 28 | Geometry | Ran out of time | Timing |
| 30 | Advanced algebra | Ran out of time | Timing |
Pattern analysis:
- Careless errors: 3 (37.5%) → Need checking routine
- Content gaps: 2 (25%) → Study word problems and function composition
- Timing: 3 (37.5%) → Pacing problem—spending too long on middle questions
Action plan:
- Practice pacing: set time checkpoints at Q8, Q16, Q24
- Study quadratic word problems and function composition
- Develop a "check your work" habit for questions under #20
Example 2: Analyzing Reading Errors
Scenario: A student missed 6 questions on SAT Reading/Writing. All were in the reading portion.
Error breakdown:
- Q3: Inference - chose answer not supported by text
- Q8: Main idea - answer was too narrow
- Q12: Detail - didn't go back to passage; relied on memory
- Q15: Inference - fell for extreme answer ("always")
- Q22: Vocabulary - didn't use context; picked common meaning
- Q28: Evidence - picked quote that sounded good but didn't support answer
Pattern analysis:
- 2 errors: Inference (choosing unsupported or extreme answers)
- 2 errors: Not returning to passage for evidence
- 2 errors: Misunderstanding question requirements
Action plan:
- Always find text evidence before selecting an answer
- Eliminate extreme answers unless passage uses extreme language
- For vocabulary, always reread the context sentence
Example 3: Creating an Error Log Entry
Scenario: Recording a specific error for future reference.
| Field | Entry |
|---|---|
| Date | January 15, 2026 |
| Test | Practice Test 4 |
| Section | Math Module 2 |
| Question # | 18 |
| Topic | Percent increase |
| Error Type | Careless |
| What happened | Calculated 20% of the NEW value instead of the ORIGINAL value |
| Correct approach | For percent increase, always use original as base: (new - original)/original |
| Prevention strategy | Circle the word "original" or "initial" when I see percent change questions |
Example 4: Tracking Progress Across Tests
Scenario: A student's scores over 6 practice tests.
| Test | R/W Score | Math Score | Total | Notes |
|---|---|---|---|---|
| PT1 (Jan 5) | 620 | 580 | 1200 | Baseline; many careless errors in math |
| PT2 (Jan 12) | 640 | 600 | 1240 | Improved checking; timing still an issue |
| PT3 (Jan 19) | 630 | 620 | 1250 | R/W dipped due to difficult passage |
| PT4 (Jan 26) | 660 | 640 | 1300 | Pacing much better |
| PT5 (Feb 2) | 650 | 660 | 1310 | Math improving; need grammar work |
| PT6 (Feb 9) | 680 | 670 | 1350 | Best score; strategy working |
Analysis: 150-point improvement over 5 weeks. Math improved 90 points (careless error reduction + pacing). R/W improved 60 points (more room for growth here). Next focus: grammar rules for R/W section.
Example 5: Identifying a Recurring Error Pattern
Scenario: Looking at error log, student notices "misread the question" appears 5 times across 3 tests.
Specific instances:
- PT2 Q8: Missed the word "NOT" in the question
- PT2 Q15: Calculated x when question asked for 2x
- PT3 Q12: Found the wrong quantity (asked for area, calculated perimeter)
- PT4 Q5: Missed "per hour" and gave total amount
- PT4 Q22: Answered for y instead of x + y
Root cause analysis:
- All 5 are careless reading errors, not content gaps
- Occurring throughout tests (not fatigue-related)
- Happening on medium-difficulty questions where student rushes
Action plan:
- Underline key words: Circle "NOT," "per," quantity requested
- Re-read before answering: Glance at question one more time before selecting
- Check answer against question: Does my answer give what was actually asked?

✅ Check Your Understanding
Reflect on your post-test analysis habits.
1. Why is analysis more valuable than just taking more practice tests?
Consider this
Taking tests without analysis is like playing a sport without reviewing game film—you might repeat the same mistakes indefinitely. Analysis reveals why you're making errors, which is information you can't get from a score alone. One thoroughly analyzed test teaches more than three tests you just scored and moved on from. Quality of practice matters more than quantity; analysis is what creates quality learning from each test.
2. How do you distinguish between a one-time error and a pattern?
Consider this
A single error could be random—everyone makes occasional mistakes. A pattern requires at least 2-3 similar errors across different tests or contexts. Keep your error log and look for recurring themes: same topic appearing multiple times, same error type (like misreading), same position in test (like errors in last section). One comma mistake is random; three comma mistakes across two tests is a pattern worth addressing. Track before concluding.
3. What should you do when you can't figure out why an answer is correct?
Consider this
First, read the explanation if available. If still unclear, it likely indicates a content gap that needs study. For reading questions, go back to the passage and find the specific evidence. For math, try solving it from scratch using different methods. If you truly can't understand after significant effort, note the question and return to it after studying related concepts. Sometimes understanding comes after building more foundation. Don't just accept "I got it wrong"—understanding why is essential.
4. How often should you review your error log?
Consider this
Review your error log at least weekly and definitely before each practice test. Before starting a test, glance at your common error types to prime your brain to avoid them. After studying a topic, check if related errors decrease on subsequent tests. Use the log to adjust your study focus—if quadratic errors are decreasing while geometry errors persist, shift study time accordingly. The log is a living document that should actively guide your preparation.
