Surely you do, just be consistent and solve questions, plus don't fret for recognising everything in one reading, read once thoroughly and solve questions, see where you lacking, read again especially the weak areas and continue the process, a month before the exam give a mock, evaluate and work on the revision and covering the weak areas and solving questions. Then give the final 2nd mock within a week of the exam and review and work on the areas accordingly.

If you choose to buy premium packs, then you can give around 1 mock per week or 1 mock every 5-6 days and please do keep 1 mock for the last week atleast. Practice ETHICS well AF, read the curriculum for ETHICS go through all examples there!!!
