Hello Aspirant,

Since only last two and half months is left for the exam.. It is very important for you to buck up and start working hard. You must understand all the concept from icai study material in next 1 month and start your revision. 1.5 months time is a good time to revise all the concept. Divide these 1.5 month into two parts.. And focus on revising twice before the exam. Also I'll recommend you to start preparation short concept register which will really help you one day before exam.. Also at least spend 12 hours per day for your self study.
All the best
