How many problems can I solve with PercenX?

Your usage limit depends on how you're using PercenX:

- Not signed in: up to 3 problems
- Signed in (Free account): up to 10 problems per month
- Signed in (Pro): up to 500 problems per month

Free and Pro monthly allowances reset as applicable to your account's usage period.

If you reach your Free monthly limit, PercenX will let you know that you've used your available questions and provide an option to upgrade to Pro.

If you're already a Pro subscriber and reach your monthly allowance, you'll need to wait until your usage allowance resets before submitting additional problems.

You can check your account and plan information from the Account area.
