Colleges in Assam

Hello Dear,
Here is a tool called college comparison app by Shiksha. You can compare any of two colleges. Here is the link. https://www.shiksha.com/resources/college-comparison
I hope this will resolve your query.

Sorry, it is not possible. Your marks are too low. You have to score around 120 marks in JEE in general category to get a good stream.

It's better to go for ECE from NIT-Silchar rather to go for chemical from NIT-Raipur.
As both the colleges are not topped ranked NITs, so here branch matters more than the college.

Hi,
Other than IITs and NITs there are many private universities like VIT, SRM, BITS, Galgotias, Nirma University, UPES-Dehradun, Amity, Sharda and LPU which are having high placement records and the decorum here will make your personality develop.

As a student of IIT Guwahati, I can assure a healthy nice environment at IIT Guwahati as compared to Dhanbad. Same is the case when it comes to reputation. I would suggest taking CSE only if you are extremely oriented to the branch. At IIT Guwahati, you can also try for a branch change after 1st year. All the best.

Last year, total 46 students opted for placement and 29 got placed with average packages of 6.9 lakhs.

Hi,
The best way to predict a college through JEE Main score is by using Shiksha college predictor.

It shows accurate results.
After that, just go for the counselling of that college.
Best of luck for your future.
Keep asking

Revise your B.Sc subjects thoroughly with special focus on microbiology, questions from all subjects such as cell biology, chemistry, immunology, biochemistry, etc. are asked only basic understanding. The Entrance Examinations for various PG, UG and Integrated Courses will consist of a Written Test of 50 marks of one hour duration and a personal interview of 25 marks.

If you want to end up with your core subject as mechanical then prefer it first but as per the campus ranking IIT, Kharagpur is better than Guwahati but I'd suggest you to do mechanical from II, Guwahati.

No, you won't be deemed eligible for admissions into IITs because you haven't qualified the cut-off set for OBC category was 64 and your score is below that. So, you can't get admission in IIT.
Explore other options and don't worry, it's not the end.
