IIT

Hello Zeeshan,
It's absolutely essential to have a dream. What's yours? Job? M Tech? PhD? Once you have dream, work towards it's achievement. But you should have plan B ready also. I feel you look for job and prepare for GATE also.

It can not be done. You will not be offered admission into IIT through lateral scheme. The reason being that Indian Institute of Technology does not offer lateral entry to Engineering aspirants. It is not possible in the IITs.
It is not just the lateral entry, you will not get any sort of admission f

Please provide me your branch and category, I will help you.

In Mains, you should score at least 50 marks to clear and 180+ in advance to get into IIT.
Best of luck.

You should get 60 to 80% marks in JEE.

You may get admission after completing your diploma if you will secure good ranks in JEE Advanced. To appear in JEE, you should have 75% marks in your diploma or intermediate (the percentage may subjected to change in coming years).

Getting admission in IITs is not a piece of cake for being successful. If you work hard on your programing, computer languages and logical ability you may become successful software engineer from any college.

You have to clear JEE Mains followed by JEE Advanced, provided you satisfy the eligibility criteria of JEE.

You can download your admit card from JEE official website.
