So for the last question I wrote out part a) and part b) and got part b wrong (as my e value was not 0<e\<1). I did part a) and b) again on the next page with part c), but forgot to cross out my incorrect answer on the page before. Will i get zero marks as there are two solutions? Or will the examiner ignore the incorrect first attempt and award marks as normal?

For the angle on the projectile, is it the angle about the horizontal or the angle about north?

I wrote both down as I was unsure

It was definitely harder than average; the poll so far shows this. Expect lower grade boundaries than usual.
