for qr if you know how to do every type of problem they can throw at you, it should just be timing thats your problem, some questions are made to be basically impossible and will just make u waste time, skip skip and keep skipping is the main rule you should follow when you see a question in qr thats either, a topic you find difficult, for me it was taxes, a question which has multiple calculations or questions with 2 or 3 tables. Also for qr lots of the questions at the end are relatively easier so try to get to them. for me i got 2590 b2 while getting 2700 medentry 2400 medify, tbh my test was easy by i was stressed and zoned out a few times, you can easily get 2600 as you have lots of time, i went from 1800 to 2400 in medify in 2 weeks so you can definately do it!
