I've just started the GMAT study. So want to give myself as much time as possible to get a good score. But not at the cost of missing the chance of gaining an interview. I won't be able to make R1 and no point in applying just before the deadline in R2 if interviews are given out before all applications are collected. I guess I'll have to sit the GMAT as early as possible as Columbia is one of the schools I am applying for.
Any idea of the policy at Harvard, Stanford, Wharton, MIT and LBS
HBS reviews applications in batch. No advantage to submitting it a minute before the deadline or a week before the deadline.
Study hard for the GMAT but not at the expense of your essays, which take a considerable amount of time. Be prepared for 120-200 hours worth of work!
