I have not revised anything at all and my exams are in 24 hours?

alumaaa
Are there any tips or stuff I should use? Also is it okay if I go through 5 past test papers and see what topic comes out the most and write the topic down on a sheet of blank paper and focus on those topics only or should i study everything? Help 😭😩
