AQA A level Eng Literature B NEA question

I’m going to be heading into year 13, my exam board is Literature B and I need help with understanding a few questions:
1) I need advice on whether the two questions we make for ourselves for our essays have to be comparison questions. Or if they can just be two conventional responses that are not related to each other, with one question only focused on the Prose Text/novel, and the other question only focused on the long narrative poem/collection of poem.
2) How long should each short poem be for it to be considered a collection? E.g. is it supposed to be 10-15 pages for each short poem? And also how long must a singular narrative poem be for it to have sufficient merit?
3)Referring to the collection of short poems, what number should the collection be? Is having 3 short poems of XYZ length A-level standard?
I need help because I’m quite worried about the coursework

Hi, I am also going into y13 but we start ours earlier for some reason...
1 For Lit B they are not comparative pieces (if you see that online I think that's Lit A not sure though) they are separate and about one text only, they are both through a different analytical lens from the critical anthology. For example: I did my novel coursework about 'Oranges Are Not The Only Fruit'- Jeanette Winterson through the lens of feminism, and now am starting my poetry piece and am planning to do it through the lens of ecocriticism (have not chosen poetry collection yet)
2 A collection of poems can be anywhere from I think 15-30 poems of varying lengths, if your teacher is the same as mine, you may be advised to read a whole collection but to choose 3-5 poems to really focus on to show depth in your analysis. In terms of how long a narrative poem must be, I am sorry but I am not sure.
3 Partially answered above I think?
Goodluck!
