Advice
It is not enough to know the physics; you must know the key words and phrases examiners are looking for. Use the examiner reports (or me) to guide you; in some years, like June 2023, the examiners have included real responses for you to compare. This is worth having a look at.
You must use all quantities provided in a question to find the final answer. This means that if you have not used one or more quantity, you know you must have gone wrong somewhere.
Calculation questions tend to follow certain patterns because there is a limited number of formulas you were taught. In each calculation question, start by identifying all the variables and writing down all the formulas which might apply.
Make sure you understand what each command word means. For example, "deduce" requires you to give a contextual conclusion, which includes an explicit comparison of values.
In the practical papers, examiners are picky about which responses they accept. I would recommend memorising the mark scheme responses for classic questions, like improving experiments or taking measurements.
There are 6 papers in Edexcel's Physics IAL. The theory papers (units 1,2,4,5) are worth 80 marks each, and your mark is converted into a standard UMS score out of 120. The practical papers are worth 50 marks each, and your mark is converted into a standard UMS score out of 60. You need 480 UMS points overall AND 270 UMS points in A2 (Units 4, 5, 6) for an A*.
