How many questions do you actually need to get right? Pick your exam and we'll use its real pass mark, or type in your own numbers for any test.

Pass mark can be a number of questions (43) or a percentage (86%) — enter either and we'll work it out.

How the maths works

Working out the marks you need

Multiply the total questions by the pass percentage and round up. Rounding up is the bit people get wrong: if the sum says 35.1, you cannot answer a tenth of a question, so the real target is 36.

How many you can afford to drop

Total questions minus the marks needed. It is worth knowing this number before you sit down, because it tells you whether you can skip a question you are stuck on and come back to it.

Percentage or number of questions?

It depends on the exam. The CSCS HS&E test and the DVSA theory tests set a fixed number of correct answers. Plenty of vocational and academic papers use a percentage instead. This calculator takes either.

A word on the numbers

The exam figures here are the ones we hold for each test on Revision Robin and we keep them current, but awarding bodies do change formats. Always confirm with the official provider before you rely on it.

Robin does the mocks, too.
