Careers360 has taken an initiative and prepared a platform named Entrance360 for all types of entrance exams. You can use that for your preparations, there you get a personalized timetable as per your requirement, proper study material, doubt clearance, test papers etc. And i believe that will be enough for your preparations. https://www.entrance360.com/
Also i will suggest that you do not worry about things like will i qualify, will i be able to make it to the top, You must only and only focus on your preparation and stay confident and believe in yourself that you can do it.

Keep practicing by solving preious year papers so that you get practice of the questions and be able to solve actual paper easily.

I hope this helps
Thanks!
