Hi Viswa,
I agree with Felix: you still have a few days left to keep practicing and improve your performance. As Felix said, it is crucial to review your answers after completing an exam simulation, with a special focus to those either answered incorrectly, or answered correctly but marked. I learned a lot during this review phase.
If you feel like you need to slightly reduce the time for review, you may want to skip those questions you answered correctly and with confidence.
One last recommendation: don't push too hard on the day before the exam. I used to review some notes, but I decided not to practice any full test. I rather rested and recharge to sit the exam the next day fully focused and energised!
Good luck on your exam,
Gabriella
