I did the BMAT last year, which is similar....I did lots of past papers and questions and brushed up on my basic maths, chemistry etc. If it's anything like the BMAT then there's not much more you can do, in the actual exam skip any difficult questions and come back to them at the end, you don't want to loose out on easy marks!!!
Lol sarah the UKCAT is nothing compared to BMAT.. Bmat seems way more easier !!!!
UKCAT doesnt rely on biology, maths, chemistry etc etc but on a comprhension where they trick u sooo much it is unbelievable !! thats just my opinion, it may be different from you but jus do practice ukcats ==> just type ukcat in the internet n u will be able to do practice papers!! hope i helped
