Hey,

Hope you are doing great as per the question asked by you you can certainly prepare for VIT by giving certain mocks and previous year questions generally there is no focused preparation of VIT entrance one generally prepare for IIT JEE Mains and entrance of VIT is covered it in as more or less syllabus is same for both the exams question level is the only key that changes.

Hope you found this answer useful.Stay motivated stay positive.

All the best!

To study for VIT you don't have to work as hard as for JEE MAINS/ ADVANCED. You should try to acquire your problem solving skills which can only be done by practicing problems. Now in general if you have moderate preparation for JEE MAINS then you will have a good chance to crack VIT. So if you target JEE MAINS syllabus and cover up in that pattern then you will prepare yourself hard enough to get a good rank in VITEEE.
