Should I attempt Mock 5 Study Hall? 2d left for the final Exam.

I attempted Mock 4 in the study hall today and scored 66%. The scores in earlier mocks were 71%, 71%, and 74%, but Mock 4's level of difficulty is literally harder than ever. I am not sure whether I should attempt Mock 5. I have my exam on Monday, 4th May. Should I solve the mini exams and focus on revision for the next two days?
