Hello aspirant, first of all congratulations on getting 560 rank in VITEEE. According to past year trends you can definitely get a seat in VIT Vellore main campus CSE branch in category 1. The tuition fees for category 1 is around 1.98LPA.

Pure CSE and CSE with specialization cannot be compared like one is a better branch than other because what branch you take should be focused only on your personal interests. If you are not sure about pursuing a specific field in CSE then you should go for pure CSE that will give you opportunity to try different fields of CSE rather than specializing in a certain field like bioinformatics or AI.

CSE specialization with Artificial Intelligence or Data science has good scope for learning and job opportunities in future. VIT Vellore does not provide specialization in AI but other VITs like VIT Chennai does. Many students interested in cybersecurity also  take CSE specialization with cybersecurity. Bioinformatics is also considered a good specialization in CSE.

So to summarize all fields of CSE have good scope in future and you should take the branch depending on your interests.

BEST OF LUCK!!
