Two good points from this debrief.
- After solving 50Q from one source evaluvate whether it was worth it, else everyone who studied more than 6-8 months would score 800.
- Not keeping all the tests for the last month, rather spacing 10-12 tests over a period of 2 months.
One point of caution though is OP seems very good in fundamentals as he scored 680 without much prep and 740 in MGMAT1, so if you targeting 760 you may be better served by getting to the 700 level first and then following up with two months of tests extravaganza.
