In your situation, I’d probably suggest the following, depending on your interests and career intentions (which from your earlier posts, I understand you want to become a scientist):
- General Maths U1/2 which becomes Further Maths U3/4: Arguably, General doesn’t take up a lot of time, basically covers some of Year 10 maths (very doable even if you didn’t do it) and isn’t “overly difficult”. Some concepts, particularly data and stats, taught in this subject will likely be crucial if you’re deadset on a scientific career.
- Psych: see Bri’s post above.
- Health and Human Development: Pairs well with the sciences, especially if you’re into the biology/ health sciences/ medicine fields.
- Business Management: A good break from your other subjects, I’ve heard quite a few people doing this “because it doesn’t have a huge workload”, though it is hearsay. Would also be good for a more varied skill set, which is becoming more necessary these days (for employment, for personal improvement, for adulthood, etc.).
