1. Dont leave anything as option - try to cover 100%, 2 months is a lot, ive seen people clear CA finals in 2 months.
2. Give as many mocks as u can
3. Dont refer anything other than institute material (IPCC question paper often comes from PM SM as it is)
4. if u feel something is tough and is taking too much time, just try to solve 2-3 questions on it from PM. even if u dont understand the solution just try to solve it as much as u can...u get marks for part solution
5. Dont under-estimate theory subjects, read 1 theory subject everyday (switch between law and audit/IT)
