My keam score is 97 and I got 89% in plus two, which our plus two mark will not be calculated this year, which rank should I get and can I get in TKM within the three rounds

Hello Aspirant

To get into top colleges with branches such as CSE, IT or ECE, you need to score minimum of 600 marks or above in KEAM 2021. With your scores you can expect a rank around 35000 or more.

You can get a detailed report of round wise cutoffs for different colleges from the link given below:

Even if you are having good marks in class 12th boards, your KEAM scores do matter for ranks.
With a score of 97 marks in KEAM 2021, it is very difficult for you to get into top colleges with any of the above branches.

Now as you have mentioned about TKM College of Engineering, to get into CSE branch you should have a rank below 1000. For this rank you need to score more than 800 marks out of 960 marks.
The branch with least cutoffs is Production Engineering with a cutoff rank of 8000 or below. So you have no chances to get into top branches.

You can try to score well in other entrance exams which are considered for taking admission into various engineering colleges.
If you have applied for any of these exams then prepare well for it.

Hope this helps
Good Luck
