Physics AS paper2 , rounding up...

[Choi WW]

There are a lot of calculation questions in physics, right? Also, there are many parts in each questions, and some of them are continuous, so we have to use the answer of the previous answer. For that case, the result is sometimes different from the marking scheme due to rounding up from the previous part, right? Thus, would they recognize it and mark it as right even if it's different from the marking scheme? I really want to know it because those kind of things look random for me, they sometimes use rounded up answer and sometimes they don't.

It is better to not to use the rounded up answer. use the exact value for calculations. and they will give you marks even if you use the rounded up value. In some marking schemes , they have written both the answers.

Thanks, a lot ^^
