How hard are isaac physics questions supposed to be?

Doing uni in singapore and I can confidently say that the Isaac Physics questions with difficult of P3 and above are comparable to uni level questions (at least those that are in A-Level difficulty). That got me wondering about how hard those questions are actually meant to be. I remember when I prepped for the AP exams and the PAT last year, and I found the exercises to be quite useful but are tricky. For those who used the site or are using it, do you find them easy/medium/hard? I didn't do A-Levels, so I'm curious how hard Isaac Physics is compared to A-Level questions. Are they meant to be that challenging, and would you compare them to Olympiad-Level questions?

Would like to see your thoughts on the site.

If you're comfortable with AP exams and the PAT, you're likely ready to tackle these problems.

Thanks!

Few additional questions:
On avg are AP exam questions harder than an A-Level question or are they roughly equal or easier?
Also is PAT similar level to olympiad?
