my 1st time taking CP1 so i can tell how it is going for me (not how it should be!) -similarly started past papers which is a great position to be in (some brave souls may just be starting the notes!) -it's normal to struggle with time and answers -beauty of having so many CP1 and CA1 past exams is that attempting and then looking at solutions helps guide/brainwash you to think like the examiner.
Two quick tips, which may help you:
1) I've found it effective to allocate less time than the exam actually allows. So instead of 2 marks a minute, aim for 1.5 marks a minute -this has forced me to speed up my thinking &typing! And remember you only need around 60% for each question, so dont aim for perfection.
2) From an Acted tutor: To cover more past paper Qs, instead of writing a regular answer &timing it etc, can just scribble a few key points/draw mindmap of answer. Before checking the Solutions and comparing to your key points/structure.
