Key takeaways
- Ask how much full-length, timed practice you get, and in what format.
- Check where the practice questions come from and whether answers are explained.
- Try before you pay: a free test tells you more than any brochure.
What should you compare before you pay?
| Question to ask | Why it matters |
|---|---|
| How many full timed tests are included? | Timing and stamina are skills; they need full tests. |
| Where do the questions come from? | Released or original questions should be labelled honestly. |
| Is every answer explained? | Explanations turn mistakes into progress. |
| Can I see my weak topics? | You should know what to practise next. |
| What does it cost per month, and does it renew automatically? | Know the real total before you commit. |
Should you mix a tutor with online practice?
Many students do: a tutor for explanation and accountability, and online practice for volume and timing. The mix matters less than doing timed practice and reviewing it.

Questions students ask
Is online SAT prep enough on its own?
For many students, yes, if it includes full timed tests, explanations and a way to see weak topics.
