Increasing marks in mocks

So, did a mock today. First time an FLT...read a 100 questions... Attempted 54....

The number of incorrect ones was more than the correct one....yep....21 right, 23 wrong!!!?

Started analysing the mistakes, but after going through a 30 questions (took 45 min), gave up. Mind was full of ifs and buts... Conclusion was that revision is required. Could not answer most of the questions (unattempted ones+ the wrong ones) because of the lack of revision.

Note to self: don't make wild guesses

How do you people analyse tests?

How many questions in one go? Do you do it batchwise...like a certain number say 25-30 or 50, then reading other subject, then again resuming analysis for the remaining questions?

Or continuous hours of analysis? (Am I the only one who find continuous analysis as  exhausting, and then do not resume to finish the remaining analysis ??)

How do you give more than one mock in a day? I mean the analysis part... same day both ka analysis or one day one analysis, then next day 2nd ka analysis? But doesn't it pile up? Fir revision kab incorporate karein?

Confusion hi confusion h, solution kuch pata nahi, 

Solution jab mila tab question kya tha pata nahi...
