hey,
for P1, i advise u to go through any text book or revision guide u have, cause they tend to ask the unexpected stuff, also u should know the diagrams to many things .. its comes a lot as well,
you have plenty of time, phys is on wednesday, and its sunday today, so dont worry, you will be fine,
and dont forget !! past papers !! and for P1 time ur self, so u dont have trouble with timings in the real exam,
wishing u the best of luck !!
thanks
