Its best if you do 2 sciences- chemistry and biology especially are nicely paired (some unis don't count psychology as a science which is stupid imo) . This is mostly because most unis require 2 sciences (+ maths) whenever trying to apply for something science-based. As interesting as psychology is, it won't open the path to optometry (i think, you can obv prove me wrong lmao).
and if you're still keen into psychology, a psychology degree at uni requires biology only.
Chemistry, Psychology and Media isn't bad imo, but, make sure you choose a range of subjects that won't keep your path closed. Have you looked into media degrees and what most require?
