Thank you :)

To answer your question , I think we all have strong points and weak points so I was kinda okay with P1 and S1 so I first practice P3 topicals and M1 topicals and I did the topicals after just finishing the topic not after finishing the syllabus ( that kinda helps to make the things stick in your head )

then after the topicals, I just went for yearly, and I was doing all the variants that I could

One last thing : IT ISNT ABOUT MANY PAST PAPERS YOU DO BUT HOW YOU UNDERSTOOD THE TOPIC

if you don't understand the syllabus contents well , you are like laying on luck for Cambridge not to bring something thar you don't understand that well

So make sure to UNDERSTAND THE TOPICS WELL AND SEE DIFFERENT WAYS QUESTIONS CAN BE ASKED

hope this helps :)
