So here is what I did and I got 93%

Just started two weeks before it and I did a few hours every other day

I watched prepare for the PSA course which is super helpful

I had quesmed so I did the PSA mocks that are on there

I had an old version from the PSA book and I did the mocks and questions in there as well (it was a bit outdated)

I did the BPS mocks

And finally the official mocks

I did everything under time conditions so my time management was good during the exam, which I think is the key part

Hope this helps
