The level of difficulty of a program depends on your passion mostly. If you are passionate about learning then an MA in psychology from IGNOU is not that difficult. You can even work while pursuing a Masters.

Firstly attend all classes and complete all practicals. You will be guided by facilitators throughout. This will help you at the time of examinations. Also, the study material provided by IGNOU is very easy so I don’t think overall it will be a difficult ride.

Ambedkar University, Delhi is a new university and it comes under the jurisdiction of the Delhi government. It is mostly known for its Humanities courses like Sociology, Phycology, Economics, etc. It has better faculties compared to DU. Almost all faculty members hold Ph.D. degrees. As it is a small institute, the quality of education offered is quite good. They also offer many subject choices for these courses. However, the placement scenario of the institute is not that good.

One of my friends studied Psychology at Aryabhatta College. According to her, it is really great as it offers immense exposure and opportunities.

• The college, though being a new establishment, is growing rapidly academically.
• The college is very strict and has certain rules and regulations to maintain its discipline. 75-80% attendance is compulsory.
• The faculty is highly experienced and cooperative.
• The department organizes guest lectures on a regular basis from eminent people in the field of psychology. 
• Srijan, the psychology association of Aryabhatta college is a very active society.
• Being in Delhi University South Campus there is the ease of transportation. 
• The student crowd is also very good.

Therefore, you can consider this college as a good option not just for psychology but for other courses as well. It might be a little less recognized among other DUs but it will surely provide you with the proper exposure.

Ambedkar University Delhi is great for pursuing a BA in Psychology. This university is well-known for its Humanities subjects such as Psychology, Sociology, etc because of its faculty base and innovative teaching methodologies. You will get to learn through practical exposure, fieldwork, experiments, etc. The coursework doesn’t get boring as students get to learn through movie screenings, presentations, projects, etc. 

It's understandable that you may be considering a change in your field of study, especially as a 2nd-year student. To determine if psychology is the right fit for you, first, you should do some research and gain a better understanding of the field. While many people consider this field as cool and interesting, the reality is far from this. 

Psychology is a difficult field unless you are genuinely interested in it and are certain about pursuing a career in it. A career is a long-term shot and you should be determined to go for a PhD from a top institute. Many times people are attracted to a certain field only to find later that they just wanted a way out of engineering. It's very necessary to do a self-analysis.

Also, I would like to clear the misconception that you don't have to get your bachelors in the same field as your master's. Unless you are planning to get a master's or doctorate, a bachelor's in psychology is not an easy degree to find a comfortable living after graduating. You can just take a minor in psychology in order to meet the eligibility criteria to enter many graduate school programs. But, if you want to pursue a research-based Ph.D. program you will likely need to get actual research experience, which may be harder if you only did a minor.

Additionally, you can read up on the latest research and articles in psychology, and explore different subfields of psychology, such as clinical, developmental, social, and cognitive psychology. It's important to remember that changing majors can be a big decision, and it may take some time to determine if psychology is right for you.
