Hello,

I would suggest you to do self study rather then joining up any Institutes or home tutors.Since you are already an ex-aakashian ;you do have the best supplies available.Now thing that is required is how much time you can devote.The more time you give to self study the better it would be.I would suggest you to join a test series so that you can evaluate your performance from time to time .Also for doubts in any topics you can take help from unacedmy platform / you tube.

Hope this helps .Feel free to ask anything further 

Dear Sir / Ma'm, self study is the most important aspect. Devote much more time to slef study. Keep your concepts as clear as possible and practice concept related multiple choice questions everyday for all the three subjects. Read everyday and revise the previous day's lessons. Study sincerely and you will succeed.
