Which one is better, a B.Tech in CSE in AOT under MAKAUT or a BSc in Psychology in Loreto College in Kolkata?

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.
