    For my coursework i calculated my % errors from my graphs. I got a huge number like 20%. Will this affect my mark?

    If you have correctly calculated the error, then you won't lose marks for the calculation, no.

    That said, a 20% error is unacceptable really. You will most likely lose marks for poor measuring technique. Can you give a bit more detail on the quantities you were measuring, and what you were using to measure them?

    Maybe you should think about doctoring your graphs to get a lower % error :p:

    Id definately double check that 20% error suggests you might have done the experiment poorly.
