I used to have that happen to me, Just do past papers and go through the examiners report, it makes you adapt to the way they think and ask stuff.
I did exactly that yesterday and got 70/72 on the June 13 paper , Although that probably is one of the easiest papers, I still don't feel I'm fully prepared so I'll need to do at least one more.
Tbh I've found the ones you've posted in the original post the most useful
These ones are pretty good as well, it's just that the MEI ones highlight key stuff really well and often give away some tricks the exam questions might use. They are meant to be paid for by the school though so unlikely to find them on the internet.
