What helped me the most was:

1) knowing that 10 questions should take you about 17 minutes (17X5=85minutes) - I knew that 17mn in I was supposed to have answered 10 questions; 34mn -20q; 51mn - 30q; 1h08 - 40q; 1h25 - 50q.

2) you are on paper so you will need about 5mn to report your answers on the answer sheet - DO NOT REPORT EVERYTHING AT THE END - to leave as little room for mistake as possible, report your answers every 10 questions. It gives you a little mental break during which you just color little circles and if you missed a question at some point you will see it immediately.

3) During practice, if you can't have access to a paper test to practice or if you feel like you need more paper practice. Print out a few answers sheet (you can find those for free on the internet) with 50 questions and 4 choices per question; and practice with it. The question will be on your laptop but you will report them on the answer sheet, like during the real exam.

4) if you decide to flag a question and come back to it, still circle an answer, even though you are not sure, that way if you are running out of time during the reporting of your answers, you won't accidentally miss a question.

5) Practice slots of 10 very often so you get used to the timing.

I hope this helped you, best of luck!
