Hiya
Difficultly wise it will depend on your own personal feelings but I will give you my opinion
Ukcat -
5 sections, required for all but a few unis
Verbal reasoning - big blocks of text you have to pull info from
Quantitative reasoning - the mathsy one
Abstract reasoning - the weird patterns one
Decision analysis - codes
You get your score immediately after, can be taken any time over a few months
BMAT -
3 sections, required by imperial, UCL, Oxbridge and soon Leeds
- aptitude and skills
- science and application
- short essay
Sat on first Wednesday of November (usually) - results a few weeks later
In my opinion (this may changed after I take the BMAT on Wednesday) I find ukcat harder because it's just...odd.
