Hii

It would be great if you start your preparation from now only as this will make it easier for you to qualify the entrance exams with great marks. But do not get busy with the preparation of entrance only, do remember to focus on your boards also and score good there also.
If you need any more help you can freely ask here on careers360.
I would suggest you to start your preparations with proper study material and proper schedule so that you dont face any problem in your boards or entrance.

Hope this helps
Thanks!
