BS business management to BS Psychology

I’m planning to shift to BS Psychology on 3rd semester. I tried to shift before the school starts, I emailed them but unfortunately they didn’t reply so i’m gonna shift 3rd semester. I’m kinda scared because I’m from ABM talaga nung SHS and anlayo ng pagsshiftan ko.

Any tips or advice to someone who has no prior experience with STEM related subjects? Are there stories of students got rejected mag-shift to BS Psych and so what can I do to avoid getting rejected? Also is there a lot of recitations ba sa BS Psych?
