Yes absolutely!
There's an option to review later
It definitely helped my husband as there was about 6 questions he wasn't sure about because of the way the question was phrased (he said) but he skipped over them and came back to them later to reevaluate and answer
I went through all the questions once using the option to review later, then went through them again, this time selecting a final answer - just my method, not saying this works for everyone

- still finished the test in about 10 minutes and got 20/20
