Should I return for S6 or go to college?

I am currently in S5 studying Higher Business, English, Maths, Modern Studies and Nat 5 Biology.

I want to study Environmental Health at Uni, which requires 4 highers with 1 in biology OR human biology

As I will have 3-4 highers after this year (depending on results), I kinda feel returning next year is pointless as I'll be taking Higher Biology plus 3 other subjects just to reach the 4 that my school require.
Therefore should I leave after this year and study Higher Human Biology at College (1 day a week course) and pick up extra hours in my retail job (allowing me to save for driving lessons/uni accommodation costs) or would I be disadvantaged by not returning for S6?

I am really undecided so any advice is appreciated

How many uni courses have you looked at?
Are the entry requirements consistent for them all?

I want to study environmental health, only university west of scotland offer it so only one uni in Scotland,

Okay, what's the back up if UWS say no?

Definitely something biology related

My advice to you is put together your plan B and your plan C.

Plan A looks very clear, and doing college part time and retail work part time is sensible for plan A. BUT, if UWS doesn't or can't offer you a place for whatever reason, what then?

More (adv) highers would give you more options. Then again, there are plenty of opportunities still to uth the qualifications you would have under your current plans.

Once you've got an ideal plan A, B and C written down, work out what next steps keep all of those avenues open to you.

I hope this is useful
