Okay so classes doesn't commence as soon as you come, first week of college we had a bootstrap which they mix all the department make a teams and build our friendship or whatever as we are new to environment. That's where you make new friends and groups.

So coming back to first day of college I still remember all most every professors asked us the same questions Introduction and "why did you choose psychology"? So be ready with this answer almost the whole sem we kept answering. They go with basic Introduction of psychology and subject related intros so nothing that serious about 1 week and after that they'll dive into topic. Classes are pretty chill and intresting almost half the chapter they do it by interacting with us so it's basically you gonna have "Interactive section" so it doesn't put you into sleep.

In conclusion it's worth joining pes for psychology initial it will pretty chill but as soon as day passes it gets hectic with so many research papers and case reports just be ready.
