Hi Jaimin,
First of all many congratulations for you achievement in IPCC.
Did someone scare you about CA finals? Do what you have been doing in IPCC. You would be having your own unique way of preparation and attempting the exams. Dont try to do anything different. You have ample time to plan your studies. Yes I understand that your articleship would be hectic, but still you can manage.
Start in advance and take the lead. Dont wait for others to start. If you need tuitions, take them up right away. Each person would come up with different advise and tip, but for a student like you that wont make much of a difference.
This however does not mean that you should not take advise from seniors. You should and their experiences would be helpful.
One last thing - dont be over confident (I believe you are not). Rankholders have failed in the past. Start the new beginning with a blank slate and chalk out your destiny.
Good luck and all the best.
