I have given combine science and I wanted to know will it effect on my college because I want to get separated science for my A-levels.
Please let me know.
It definitely shouldn’t as I take combined and I meet the requirements to take single bio next year for my A levels. Check the sixth form/college you plan to go to just to be sure of any specific subject requirements though!
My high school never gave us separate science as an option and when I left for college where most of the other pupils did do separate science in my physics and chemistry classes I found that some of the earlier fundamental topics were rushed over because I was just expected to know them from separates and therefore my grades flagged for the first half of my first year.
However, you could easily do combined science and do a little studying ahead on the crossover topics from separate science to a-level and do just fine.
