Polytechnic

Dear Charles, there is no age for learning. So, its okay if you have 3 years gap. Submit gap certificate and take admission. You can appear for LEET exam or go for university specific exams or even go for direct admission subject to fulfilling the eligibility criteria. Universities like LPU, DIT, Mangalyatan, Chitkara, etc. Are offering B.Tech Lateral entry. All these universities have wonderful infrastructure and world-class facilities to offer to students apart from good placements. Some even offer scholarships to meritorious students. Good luck.

First off all you should get at least above 90% aggregate of level subjects. Also, do some research on good colleges for your branch, see the last year cutoffs, placements and overall ratings. Even these all things will matter but the very first thing is your marks so work hard and get good marks. All the best.
