## What are the steps?

## How to use VPR Prep

A four-step practice loop.

1. **Take the diagnostic** — Create a free account and take a short diagnostic. It shows where you stand before you plan anything.
2. **Sit a timed mock test** — Choose a test from the calendar and attempt it in one sitting, with the timer on, as you would in the exam hall.
3. **Review the scorecard** — Open the scorecard and read the explanation for every question. Note whether each mistake was a knowledge gap or an exam-hall error.
4. **Revise and repeat** — Revise the weakest topics first. Then take the next test and compare.

## Why timed tests?

Knowing a topic and recalling it under time pressure are different skills. Timed tests train both. Our guide to [mock test analysis](/blog) explains how to read the result without wasting a single mark of insight.

## Frequently asked questions

### How often should I take a mock test?

Most students do well with one full test a week alongside topic revision. Increase the frequency as the exam gets closer and your revision is complete.

### Do I need to review questions I answered correctly?

Yes. A correct answer reached by a guess hides a gap. Reading the explanation confirms the reasoning.

### Where are the test dates?

On the test calendar page, which lists published tests with their timing and coverage.
