"The great thing about Smart Worksheets is that it tells you at every point whether you’ve got it right or wrong, what might be wrong and how you might go about changing it. The students found that really valuable. In their exam, we found that the average mark in the maths questions rose from 59% to 79%, which made a really big difference to the student outcome.”
