if PT is heavily relied upon to judge fresh grads, then the journey for most fresh grads end because of the PT result. There are too many exam smart local students.

Your question on cut-off, I assume means score. You need to understand that PT is not PSLE for the highest score. It indicates traits of a person and their intensity. Some jobs need strong numerical and focus, some jobs don't prioritize these. Think of accountant vs salesman.

However I would encourage everyone to score for section A and B. It's always a bell curve. If 4 people all get 50% you gets 60%, all the results are not great but guess who gets priority anyway.

I dont have a model answer, but I hope this helps.
