Resitting a few GCSEs in my gap year

I'm planning on doing this. If anything, it'll look GOOD - you're showing that you recognise where improvements can be made and can spend your time catching up to standard when necessary. Don't try to hide it. You're showing humility and self awareness by retaking GCSEs while others are lounging about on a beach in Thailand.

Thanks for the response. The grades I got before were alright but I know I could have gotten A*s in them. What are you planning to do at uni?

No problem! I have to ask, though - why are you retaking GCSEs just to get A*s? Unless you got less than Cs, your A levels are more important.

I'm considering veterinary medicine or maybe veterinary nursing, depending on my A level grades. What are you planning to do at uni, and have you checked whether unis need A*s? If you don't need the A*s then it's likely you'd be better off doing something more productive during your gap year.
