Hello

Well I will give you a gist of both the colleges so that you can decide which one you prefer.

St Xavier's Kolkata- Ranked 6 for Commerce (https://www.shiksha.com/accounting-commerce/ranking/top-commerce-colleges-in-india/97-2-0-0-0) by The Week 2020. Well as per the reviews by most of the students here, the faculty is good buyut the course curriculum ic a bit outdated. In term sof the campus life, it is great and there are hostels too. They have a cultural fest every year (a oretty big one). The placement opportunities are good as top notch companies visit the campus however the competition is really high.

Ramanujan College- Ranked 42 for Commerce (https://www.shiksha.com/accounting-commerce/ranking/top-commerce-colleges-in-india/97-2-0-0-0) by India Today 2020 . The students get placed here but the percentage is 40 to 50 percent of the total with an average salary of 3 lakh per annum. Besides this, the faculty is highly qualified and the course is up to date. There are a lot of clubs and activities and the campus is great however it does not have a hostel facility of it's own.

In my opinion, if you are a very studious and study oriented person then go for St Xaviers but if you want an all round development with sports and everything then go for Ramanujan.
