Look because the ucat is so skills oriented, last minute changes to strategy itself are probably seldom going to lead to improved results. I did completely flip my VR strategy a little under 2 weeks before the exam which I wouldn't necessarily recommend, but I wanted to trial a new approach because my vr results were below what I was hoping for. For reference, I moved from an approach where I would read the question/answer option of q1 first, then read through the text until i reached the info required to answer that question, then read q/a of q2 and continue to an approach where I would read the entire passage first in roughly 60-75 seconds and then answer the 4 questions in the remaining 45-60s. The one I used today isn't the most popular or necessarily recommended by most experts but a tutor who got 900 in vr last year said it helped him so i thought why not give it a go.this is a nice summary, what time your exam was? any last minute changes or last minute cautioning points.
What was your scores in OQB mocks A B C D?
The biggest cautioning point that I believe will reduce a lot of people's scores who really should be getting higher is becoming too much of a perfectionist and not wanting to move on from any question before they are confident they are correct. This is often not much of a problem in mocks because you subconsciously know that skipping a question isnt the end of the world because its just a mock, but when you get into the real thing and you know that every mark may count, it can be very hard to flag and skip something hard and then come back at the end if time allows. I fell into this trap last year for DM and didn't finish the last 4 questions (which are probability questions and are generally pretty easy). Only two ways of overcoming this are either to focus on it in your ucat practice or to walk into the exam with the knowledge front of mind that you need to continue moving through the test.
Because I sat the ucat last year, I had already completed all the official mocks last year, so my results may not be completely valid. Nevertheless in April i got 29/44vr 28/35dm and 25/36qr on mock A (can't remember what happened with qr but this was considerably below my other avgs). in May i got 29vr 30dm 31 qr on mock b. In early June I saw considerably improvement on mock c 39vr, 31dm 26qr, then a week later on mock d i got 38vr 28dm 35qr. Funnily enough the 39 and 38 vr were both with the old strategy that i got rid of.
Hope this helps! Let me know if you have any more questions, I know how stressful ucat can be so I'm more than happy to help
