As you might have known, UKCAT stands for United Kingdom Clinical Aptitude Test. If you want more info about the test, try their official website. http://www.ukcat.ac.uk/registration The cost is still £100 and you need to register yourself before 19 September for this year (2014). I took my UKCAT in 2012 at the University of Sheffield's office. Make sure to book early because the places are limited or you'll end up taking ukcat at Singapore or Indonesia. Your UKCAT mark is very, extremely, remarkably, terribly IMPORTANT for your application. When all other applicants have that all great results, what makes you stand out is your UKCAT mark and of course, your personal statement.
I went to the office by ktm>lrt>taxi from Nilai. Alhamdulillah we (Ardilla and me) made it. The test was as expected, increasing in difficulties and (I regretted it now) for the abstract reasoning I was too carried away trying to figure the pattern and didn't manage to answer all of the question. #note:even if you didn't know the answer, just pick one. At least you have a chance of getting the right answer rather than a 100% wrong because you leave it blank. This site has awesome tips and tricks, try and have a look at it. http://graduatemedicineapplicant.wordpress.com/ukcat/
Last but not least, you'll get your results a few minute after you've finished your test. So, brace yourself. Whatever happen just don't give up and hope for the best. :)
