Scoring 430/500 in CBSE Class 12 is excellent (around 86% aggregate ), and it makes you eligible for admission into Computer Science & Engineering (CSE) in most engineering colleges across India. For government colleges like NITs, IIITs, or GFTIs, you will need a good JEE Main score in addition to your board marks. If you’re open to state-level institutes, exams like KCET, MHT-CET, WBJEE, or TNEA can help you secure a seat in reputed colleges. With your strong marks, you’ll also qualify for many private universities that admit students based on Class 12 performance plus entrance exams.
