Need advice on scheduling GMAT

Hi All,

I have been preparing for GMAT since last year alongside my job with some breaks in between. Now I exhausted GMAT prep mocks 2 times each with score of 690 as highest. I am also using experts global test series. With change in select section order and some change in time management strategy alongside practice I got 750 (Q49 V42-first time crossed V35-first time ever crossed 700) in experts global mock post a 630 in gmat prep mock. Today again I gave a gmatprep mock (5th attempt) and got 730 (Q50,V39). My test selection order usually is quant verbal IR and AWA. Now I am planning to write one more mock after some days and try to score 700+. I now have to quickly finalise and schedule an appointment as prep is being stretched for quite some time now. Kindly advise when to schedule the appointment based on the mock cats and how to assure myself that if I am scoring 700+ in mocks I can repeat the same in actual GMAT. What things should be kept in mind??

Also I haven't really decided on list of schools to apply though i have a vague idea of some schools that I would be interested in. If I do not apply this year and instead apply next year will this have any impact? I hope my scores sent to these B schools will be valid for my application.
