Yeah I found it quite difficult too.
We haven't covered harder 3U yet, so we had a multiple choice and 2 other questions removed (I believe a circle geo and Q16 or something) and replaced with some Independent questions.
Felt fairly prepared going in honestly but was pretty shocked for the first half hour or so. Overall not really happy, but hoping for around 65+/100 or so
yea the harder 3 unit was hard, cause our school finished all the content, legit could get like 9 marks from question 16, l think every other question was actually decent, l think l probably lost like proabably 2-3 marks maybe on each question.
