JEE

Firstly, you have to fill your details and choices of Your IHM and then wait for the 1st round counseling. After counseling, you have to pay the fees and go for documents verification at your regional centre.

Hello, I hope you are doing well. You can check the list of colleges including NITs and IIITs that you can get according to your marks and rank. Use Shiksha JEE college predictor:

If you follow this for one week, I guarantee your confidence will boost enormously. For physics, read NCERT first and then do the exercises. Then go for HC Verma and solve exercises. HC Verma's theory can also fetch you good marks in boards. For chemistry, just go for NCERT, nothing else. Read it once twice thrice until you become confident. For maths, first NCERT and then any other book recommended by your coaching. Also, remember to take the test every week for boards from Arihant or other sample papers.

Yes, you can correct it, but generate your password while filling your choice.

Hi there,It would be very difficult to get admission through this score in JEE. Now JEE solely considers the marks obtained in JEE as the rank determining factor. Class 12 marks are not being added like previous.

No, you cannot get admission in the NIT or IIIT, as your rank is very high. You can get good government and private engineering college like Nirma University, Chandigarh University, Galgotia University, Amity University, JECRC College JaipurArya College Jaipur, Poornima engineering college, Jaipur

No, you cannot get seat In NIT or IIIT, but you have an option of best private universities and colleges like,
Nirma university, LPU, Chandigarh university, Amity university, JECRC, Poornima college Jaipur, Arya College Jaipur, SkIT Jaipur, Galgotia University and many more are there. You can search on google according to your location. At least you should fill the form for the JOSSA counselling. You may get any good college. All the best.

With such score, government colleges seems quite tough. Try applying in some good private colleges.

Well you have cleared your boards exam with 77% but your JEE Mains marks are very low. Having SC category quota might help you to get a college for civil engineering.
