Converting from binary to decimal and back again is a key skill for Computer Scientists at GCSE and above. Students also have to be able to convert to and from hexadecimal.
This means that there are 6 possible conversions that students need to be able to make in a Computer Science exam:
I’ve updated this free tool so that you can generate 20 questions to test yourself (or your students) on any of the six conversions above. The self marking computing tests let you choose which conversions you want to practice and will give you an accuracy and speed score as well as a final score for the number you manage to get correct.
