luvmins I ended up deciding to do law and hopefully do a double degree in either law/business, law/commerce or law/compsci. I do chem, bio, pysch, english, design and general maths (dropped out of methods in term 1 lol). As for UCAT, it really just comes down to how much your capable of. If you still want to go into med and think your able to start UCAT prep now then def go for it.
There are a few uni's that don't require UCAT, but each of those have their own admission system, and some uni's only offer medicine as a post-grad degree.
