I think I got something like 4 on the nuclear one and 5 on the Astro (dropped one mark for not stating value of hydrogen to helium ratio but had every other point)

Woah that's impressive! You seem to have a knack for 6 markers haha.
I literally just finished my AS physics exam. If you are not comfortable in the exam it's because either the chair is too small or the table is too high lol

What would people say is the best method for remembering the absorption lines in spectral classes?
(Ignore attachment).
I don't think there is a method, apart from learn OBAFGKM and learn the absorption lines in the same order and that they go with the corresponding letter.
He+ He H He H H Ionised metals Ionised Metals Ionised and Neutral metals Neutral metals Neutral atoms TiO
They kind of go in an order. I haven't figured out a way of learning it I can just repeat them in that order and I know they go with OBAFGKM

Thank you! Are Balmer lines mainly prominent in class B, or is it all of O, B and A?
