You need to look at how you are using Maths Whizz as it will get hard quickly if you simply keep going on thru the next lesson every time a test is passed. Go into the 'bedroom area' and you can continue doing other examples to reinforce learning in the different areas e.g. shape and space or whatever, and choose the level, e.g. same level, lower level than your child is working on. They should do more reinforcement a week than new lessons.
