I am currently in Year 12 and I do biology, business and psychology. I want to do dentistry which i have realised just now but i am not sure whether or not I should resit Year 12 and take chemistry instead of business. I've done a bit of research and I've seen that i would be able to apply to the University of Plymouth and KCL with my current A levels and i wouldn't need to do a foundation year. I would also be eligible to apply to the University of Bristol, the University of Manchester, the University of Plymouth and KCL which offer a foundation year for dentistry. However if i resit Year 12 and do chemistry i would be able to apply to Bulgaria if i don't get an offer in the UK and i would have a lot more options in the UK as well . So should i resit Year 12?
