UCAT score plateaus are frustrating, but they are common.
If your scores are not improving, the answer is usually not “do even more random questions”.
You need to work out why progress has stopped.
Start by looking at section-level patterns. Is one section holding your total down? Is your accuracy fine but your timing poor? Are you making the same type of mistake repeatedly?
Then look deeper.
Maybe your Verbal Reasoning accuracy drops because you rush the last few passages.
Maybe your Decision Making errors are mainly probability questions.
Maybe your Quantitative Reasoning speed is good but your arithmetic accuracy is weak.
Maybe your SJT answers show a repeated misunderstanding of escalation.
Once you know the pattern, the solution becomes much more specific.

Building Your Plan
You may also need to reduce your question volume temporarily. If you are practising constantly without enough review, you may be reinforcing bad habits.
Go back to untimed work for the weak skill. Relearn the method. Then add timing again.
Another possibility is fatigue. If you are doing too much, your scores may flatten because you are mentally tired.
Take a short reset, then return with a clearer plan.
Most plateaus are not proof that you have reached your maximum. They are signs that your current method is no longer producing progress.
Change the method, not just the number of questions.
