You need to give JEE Mains and qualify it. At least for admissions in HOME -STATE and general, you need around 148 marks in Industrial and production. Moreover, you need at least 190 marks for getting a top notch as CSE. Through JOSAA, apply through the online portal the dates for the first round is from 15th June and 25th June.
Best of luck.

Assuming you are from General category, getting into CS is tough for you as for out state students, last year's cutoff was 180 and that too for home state. I would suggest you to get a college in Jaipur or Udaipur with home state as most of the seats in sits are filled by home state itself. Else, try for private colleges with better placements.

You need all the documents required by NIT for admissions. Do not worry about everything else. For NIT, You need your 12th marksheet and school-leaving certificate. Admissions have been started from 15th June itself and the first round will go up to 25th June.
Best of luck.

SGSITS is good for placements. Being an autonomous institute, the companies prefer it over, private colleges of the region, The highest package one recruited was Microsoft through campus placements of around 24 Lacs per annum. Moreover, if you are in one of the core branches of GSITS, you'll get recruited as the number of students are not more than a certain number and every year, there are around 95% placements. Best of luck.

For electrical branch, the cutoff for home state was around 30 thousand and that for other states was 26 thousand for all India for General students. If you are around it, you have higher chances of getting in it. Going marks-wise, around 170 marks will easily get you EEE branch.
Best of luck.

The admissions are done on the basis of JEE Mains marks through JoSAA counselling. The first round of which has started on 15th June and will be there till 25th June. So, admissions are started for GSITS and you are required to fill your choice through JoSAA's official portal.

Sorry, for every stream in engineering, you should have science with compulsorily added with MATHS in your 10+2.
Your PCB will be needed and valid for all pharmaceuticals and medical-related streams (not involving engineering).
Hope it helps.

Yes, if you have home state quota, you can even go till the CSE and ECE. Else, you are definitely up to ECE, EEE and rest all branches below. Last year's cutoff for CSE was 21 - 22 thousand for other state and around 24 - 25 thousand for home state CSE.
Best of luck.

With your given marks and assuming general category, you will not be able to get into CSE and any branch of IT.
I would suggest you to go for private colleges of Indore as they have good placements such as Acropolis, Medicaps, etc.
Moreover , the cutoff for HOMESTATE for CSE and general is 25 thousand to 26 thousand and for non - home state is 21k - 22k .
Best of luck.
