Take breaks!

I am going to take my AWS solutions architect associate exam tomorrow and am just reviewing everything. I have been studying for this exam for 3 hours already with 3 hours more to go. I am not feeling really confident about this exam and I don't have time to review again so my best resort is to just wing it and hope I do well.<br><br><br>I wanted to ask if it would be a good idea to take breaks. I have 3 hours left to review. I have 3 different apps to use to review this exam so it's been pretty nice using multiple apps instead of one. I don't know how I would be able to retain all this information if I only used one app.<br><br><br>If you were me, would you take a break or keep pushing through? I could take a 15-30 minute break and then come back to it. I don't know if I will just forget everything I've reviewed so far.
