Can I get IIM A or BLCKI??

79.5 in 10th
75.2 in 12th
Will get a 7 in grad as well (from a tier 3 or maybe 4)
No work ex..

Starting Mid-July....
How much percentile do I need? I'd be happy with FMS too

I think that I can at least do good in VARC and decent in Quant too. I haven't started DILR.
In VARC, I have good reading speeds and good accuracy for someone just starting out. Will start mocks for VARC in July itself and looking to start other sectional mocks in September.

I have wasted a lot of time and couldn't start subjects other than VARC and just feeling overwhelmed.. Its has been a rollercoster of confidence and motivation for me.
Any advice???
