# Check your answer and understand what to fix

Enter both the question and your proposed answer. ExamNinja checks the reasoning, identifies missing conditions, and explains what should be verified.


## Answer checking is different from answer generation

An answer checker starts with your work. It can identify a missing step, a factual mismatch, or an unsupported conclusion while keeping you involved in the problem.

### A strong answer usually has

- A direct response to the exact question
- The essential reasoning or calculation
- Correct units, definitions, and assumptions
- No claims that exceed the available evidence

## Frequently asked questions

### What does the AI answer checker review?

It compares your proposed answer with the question, checks the reasoning and conditions, and highlights material that appears incomplete or uncertain.

### Does a positive check guarantee my answer is correct?

No. The checker can share the same missing context or factual limitations as other AI systems. Verify consequential answers independently.

### Can I check calculations?

Yes, when you include the complete calculation, units, assumptions, and requested method. Recalculate important results independently.
