Hi. I'm really confused at the moment regarding whether I should retake some units in A levels or not. I'm going to study Economics for undergrad and already got accepted to a university of choice, but my grades in Chemistry and Physics plummeted down to C and D respectively in IAL (got better grades in IAS). Most of my friends and teachers said that this will not affect my postgrad studies or PhD, but I'm not entirely sure. Should I retake a few units to improve while doing uni or will that be too pressurizing?
