Hello Aryan Jha. I study in Delhi Technological University, so I feel I would be able to help you in this regard.

Now, t he candidates seeking admission to the B. Tech lateral entry programmes should possess a state diploma of three years in any branch of engineering or equivalent examination from a DTU recognised university. The candidate should have secured a minimum of 60% (50-55% for SC/ST) marks in all semesters aggregate.

I would obviously prefer DTU. It is one of the best colleges in Delhi-NCR and is quite affordable as well. I don't understand why you would leave a good college and go to GGSIPU.

Please don't make such a decision and leave this golden opportunity to cry upon.

Also, see here, my previous answer: https://www.careers360.com/question-after-completing-diploma-can-i-give-dtu-leet-and-ipu-leet-for-btech-2018

Hope this helps you. All the very best!
