Science

Psychology is a liberal subject. It doesn't fetch jobs automatically. Study everything fully and answer well. If you are well-read, you will get name and money.

Why should you have any doubt?I am sure that you will get more than a first class. But, don't depend on a few important questions. Read the entire text. Keep your notes and records systematic. Don't waste your time.

Find a research orientation first. Good jobs are always delayed. Without Ph.D., you can't go very far. With Ph.D., you can get a government job, in colleges.

I am sorry that all good jobs are difficult. When you go high, you are answerable for everything. Only, a clerk is not answerable. Jobs are not enjoyable and money is never given for nothing.

German universities do not follow any ranking, they are equally good and competitive. The most popular ones in terms of research activities, employability rating, international orientation, etc. are:
1. Tu Darmstadt
2. Tu Kaisserslautern
3. Tu Munich
4. RWTH Aachen
5. ULM University
6. Illmenau institute of Technology
7. University of Stuttgart

Calcutta University, University of Burdwan, Vidyasagar University, Presidency University, Jadavpur University, St. Xavier's College are some of the best options. You may choose the best as per your percentage.
