My scores are around 172-178 right now. (Still choose wrong answers

The problem is that, because there are questions I remember the answers, the time management is somewhat awkward.
If I skip the ones I remember clearly, I get too many minutes unused while if I take a look at all the answer choices, the method I do not use in actual test, I run out of time.
What would be the best method to get the most out of already practiced PTs?
Thanks in advance.
