Why can't I re-begin the evaluation of level test following a lost of all answeers when my system closed down?

I was almost finished the level evaluation test when I inadvertently logged out.

However when I returned clicked on finish test to bring back the work and was told I had 0% correct with nothing answered (not true). Why can't I access the test again or a similar one? I'd like to know the results. Now the system is choosing work for me based on 0% knowledge.

Can this be rectified?

Thanks,
