QUESTIONS
1. Already took GMAT 4 times (550 -> 650 -> 660 -> 690, AWA 6, IR 7/8). Would the Adcoms (and You) think I'm crazy/immature if I retake the GMAT the 5th time to break 700 (strongly believe I can do so this time )
Or should I instead try to submit to 1-2 schools in R1 (it's pretty late already ) and count on luck in R2?

2. Are the above schools all long-shots to me?

Thanks so much for your time!
