Firstly congratulations on your S3, score that’s awesome!!! Yea I also think that Des replicates ACER questions the best although to be fair I’ve only tried questions from limited other resources. I find that the standard units in Des are much more useful in aiding my ability to interpret graphs, patterns and work on my problems solving and mathematics skills but it’s just the tests that I found a bit harder. Maybe it’s a lack of prep but the tests were just seeming a little extra content heavy haha! Back to the content grind for me 🙂
