Guys,
You might break the paper up this way

o the non visual part first.If you out and out crack it,you're there in the 99.3+ bracket already.
Now if you manage to crack visuals as well in,let's say,40 minutes or so, you will get a 99.8+ for sure.Now the reason why getting 99.8+ is a bit of a challenge is:
1.People haven't developed speed and accuracy for the non visual part,which by the way,is just an easier version of similar questions of most entrance tests.
2.People aren't able to crack visual thoroughly.See,cracking 12/20 vs18/20 is what makes that critical 6 mark difference that may make or break your chance for the top schools.
So just prepare your speed based questions(maybe do sectional tests etc.) and at the same time strengthen your visuals.(It shouldn't be that sitting in the exam hall, you're whacking your brains out on those 4-5 questions of VR that JUUUUSSSTTTT seem to be solvable but you miss some link somehow because of lack of practice).
ATB!!Happy preparations!!
