Ask an MBA Admissions Consultant

Ok, I really want to get into a business school by next year so I am trying to go all out here. I am curious if anyone here has done that and any tips would be greatly appreciated. I have a list of about 10 schools i am interested in and mostly on the east coast. I am advised to apply to all the schools with ED for "better" admit chances and the rest I will be applying till the R2 deadline hits which is ~jan next year. The way the admit timeline works is bad for me because I really wouldnt know the results till mid to late R2 for many schools and R3 is tougher. So is "applying till end of R2" a good strategy or there's a better one?
