It is good overall, but nothing beats the computer science department at any of the old IITs. Still, if you are not getting any of the main branches in IITs, you should go for it.

Alternatively, if you are really passionate about CS and you are not getting it in any IIT (which, I believe, is pretty obvious from your question), you should consider taking an NIT.

• NIT Calicut is regarded as one of the best NITs, with a strong CS department.
• You will have no problems with placements because they are quite good over there.
• You can speak with any alumni or a current student over there, they are extremely cooperative.

3. There are four messes in NIT Calicut, and one of them is pure-veg. Its mess food is better than other institutes such as IITs and NITs. It also has a night mess opened from 9 to 12.

Therefore, the NIT Calicut CSE department is good. After you get promoted in the second year, you will start enjoying your campus stay. The campus is also beautiful. The Calicut climate is also good, most of the month it is hot and rains in one semester. So, you can choose CSE if you're passionate about it.

The placement cell of NIT Calicut is good and is equal to other IITs. The non-Indian companies offer more than 28 LPA to freshers unlike the Indian companies. So there always remains a misunderstanding among candidates about the salary package offered. They used to think most of the companies offer a 40 LPA salary package, but these only include the companies in the US. Even Google India, Codenation, Directi offer not more than 24 LPA to the students. Based on these salary packages offered we can see that placements at NIT Calicut are really good.

In the following table, you will get the basic placement details of NIT Calicut.

NIT Calicut was consistent with a 99% placement record, offering students an average salary package of 8.5 LPA which gradually increased to 9-12 LPA. Most of the domestic companies do not pay a higher package than INR 28 LPA to freshers. Even MNCs located in India offer packages lower than INR 40 LPA. However, the placement cell of NIT Calicut is good. Almost all students got a placement through a college campus. So, don't just go by the statistics, also talk to ex-students of that college and you will get to know the original salary packages offered to them.

Therefore, you can join the CSE department of NIT Calicut as it has a good placement record.

NIT Trichy is considered one of the best NITs, especially for computer science. The cutoff for the CSE branch at NIT Trichy closes around 634 for OS General and 4358 for HS General, according to 2020 trends. Considering your marks the expected rank will be around 3500. As per previous years, admission stats and cutoff getting CSE with 212 marks will be difficult. 

It also depends on factors like whether you are eligible for the home state advantage or not. Students also get an advantage based on their caste as a certain percentage of seats are kept reserved for them. If you belong to the SC, ST, or OBC category quota then you may get computer science. To be on the safer side a score of 280+ is sufficient to get computer science in NIT Trichy. 

With 212 marks you will definitely get a chance in CSE at comparatively newer NITs such as Durgapur, Jamshedpur, Patna etc.
