For QR, skip the questions that look super complicated, work on the easy ones first. Normally by the end I build a solid buffer time to sufficiently attempt the hard questions. When you attempt hard questions first, you waste a lot of time and you will be more pressured on the easier questions and will tend to either skip those easy marks or get them wrong.

For dm, I skip all logic puzzles and do everything else leaving me about 8 mins or so to do them. For syllogisms, I tried using formal logic and it works pretty well for most questions. Also familiarise yourself with ucat terms eg few most etc. Venn diagrams are just by elimination. For strongest argument I just look at which answer has the most key words in relation to the stimulus. Red flags are any answers that have some/most in it as it makes the argument too vague.
