    Exceeding 1 is possible for sure. Firstly, in real life there are materials with a coefficient of friction greater than 1. Secondly, there was a m18 question that told us to prove that the coefficient of friction is 4/3. But 5 is too high, thus that method is incorrect

    Haha, it was easy for me, but others found it challenging. So this is based on how everyone in my batch responded, not just me ;)

    people got common wrong answers, which means it was tricky to some extent.

    Yeah common wrong answers show that there was a trend of difficult questions, so you might expect thresholds to be low. Maybe lower than last year's.
