How to Use Your Practice Accuracy to Estimate Your LSAT Score
One of the most disorienting things about early LSAT prep is not knowing where you stand. You're answering questions, getting some right and some wrong, and you have no idea whether you're on track for a 158 or a 168. That uncertainty makes it hard to plan — and it makes every wrong answer feel worse than it should.
There's a practical fix: use your section accuracy to estimate your score. It's not perfect, but it's a useful benchmark that takes about two minutes to run.
How LSAT Scoring Works
The LSAT is scored on a scale from 120 to 180. Your raw score (number of questions correct) gets converted to a scaled score using a curve that varies slightly from test to test.
A typical LSAT has about 100-101 scored questions across the five sections (two LR sections, one RC, one AR, plus an unscored experimental section). The conversion looks roughly like this:
| Raw Score (out of ~101) | Approximate Scaled Score |
|---|---|
| 101 (perfect) | 180 |
| 95-97 | 175 |
| 88-91 | 170 |
| 80-83 | 165 |
| 71-74 | 160 |
| 61-64 | 155 |
| 51-54 | 150 |
The curve is roughly 1 raw point per scaled point in the 155-170 range. Each question matters.
Using Accuracy Percentages to Estimate Your Score
If you don't have a full practice test score, you can estimate using your section accuracy. Here's how:
Step 1: Get your accuracy percentage for each section from your recent practice.
- Logical Reasoning: what percentage of LR questions are you getting right?
- Reading Comprehension: your RC accuracy?
- Analytical Reasoning: your AR (logic games) accuracy?
Step 2: Apply to the question counts. A typical LSAT has approximately:
- Logical Reasoning: 50-52 questions (two sections)
- Reading Comprehension: 27-28 questions
- Analytical Reasoning: 22-24 questions
Step 3: Estimate your raw score. Multiply each section's question count by your accuracy percentage to get estimated questions correct. Add them up for your estimated raw score.
Step 4: Convert to scaled score using the table above.
Example
Say your current practice accuracy is:
- LR: 72% (you're getting about 72% of LR questions right)
- RC: 65%
- AR: 55%
Estimated raw score:
- LR: 51 questions × 72% = ~37 correct
- RC: 27 questions × 65% = ~18 correct
- AR: 23 questions × 55% = ~13 correct
- Total: ~68 correct
Looking at the conversion table, 68 correct corresponds to roughly a 158-159.
What Your Estimated Score Means
Once you have an estimated score, compare it to your target school's median LSAT (see our T14 score guide for specific numbers).
The gap between your estimated score and your target tells you how much work you have ahead:
- Gap of 0-2 points: You're nearly there. Focus on consistency — eliminating the careless errors that show up under test conditions.
- Gap of 3-6 points: A focused 2-3 month push on your weakest section should close it.
- Gap of 7-10 points: Meaningful work ahead. Identify your weakest question types and drill systematically.
- Gap of 11+ points: You'll need a full prep curriculum and several months of consistent study.
The Limitations of This Approach
This estimate is a rough benchmark, not a prediction. A few caveats:
Practice conditions matter. If you're doing untimed practice, your accuracy is probably 5-10 points higher than it would be under timed conditions. Apply a haircut when estimating.
Question difficulty varies. The questions you've been practicing may not be representative of full test difficulty. Official practice tests tend to be harder than many third-party question banks.
Section weighting matters. LR is worth more than AR because there are more LR questions. A student who's weak at logic games but strong at LR may score higher than their AR accuracy suggests.
The Faster Way
Doing this calculation manually every week gets tedious. CogentLSAT tracks your accuracy by section and question type automatically and surfaces your estimated score range as you practice — so you always know where you stand without the spreadsheet.
