Engineering Entrance Exam

It is better to wait for the rank. Until the rank come it is very hard to guess. Once the rank come it will be very easy to guess whether you will get it or not.

MCA is a PG course. In order to pursue any PG, you need to complete UG like BCA or B.Sc in computers.

It is quite difficult for you to get admission in JJ School of Architecture.
It's better to try in some other B.Arch colleges.

There are less chances for you to get admission in any of the IITs as your score is quite good, but not sufficient to get into IITs. Use the rank predictor to know your rank and if you are under top 8000, you can get a good IIT with good branch.

Dear Sethupathy,
If you have lost your mobile with sim, you can still apply for a duplicate SIM by blocking the previous one. Alternatively, in case you have registered your email you will get notifications through mail also.

good luck.

You can get admission to B.Tech on basis of your JEE rank. There is another government college IGDTUW Indira Gandhi Technical University for women, Kashmir Gate. One of my friend got 6000 rank in her JEE. She took admission in IGDUW B.Tech software engineering. There will be councilling session. You can try. In Delhi there is IIT also for admission to engineering where your JEE advance rank would be considered. You can look for private colleges also like Amity and Sharda university. All the best.
