Loreto is a better option for doing a B.Sc degree in Psychology. Loreto offers great academics. The faculties are well-qualified and helpful. They will help you with your doubts even after class. However, you should know that Loreto is quite strict regarding its rules and regulations. If you don’t have any issues with their rules, you can easily fit in. 

Among the colleges mentioned, Loreto is definitely the better choice. It has been consistent with its academic excellence and discipline. The Economics department of the college is one of the best with excellent faculty. Also, Loreto has witnessed university toppers from this department before. If you are getting Loreto, you should go for it. 

You should decide which option is best for you. However, you should keep in mind that, doing a B.Sc Hons degree in Psychology will not offer many job opportunities. There are many students with such degrees and very few job possibilities. On the other hand, doing a B.Tech in CSE from AOT will give you three options. You can choose to go for higher studies. You can get decent job offers in the technical and non-technical fields after you complete your degree. 

As one of my friends studied in Loreto College Kolkata, let me share some facts about it:

• Loreto College is one of the reputed institutions in Kolkata.
• It is famous for its English and Humanities department, but Economics is also brilliant here as well.
• There are a lot of seminars, the most prominent being Ecolore which is the department's annual event. 
• The teachers are very helpful and cordial. 

If you want to pursue Economics, Loreto College will not disappoint you.
