No not a problem at all!
Well here is the new spec for English Lit B for your first AS year
http://filestore.aqa.org.uk/resources/english/specifications/AQA-7716-7717-SP-2015-V1-0.PDFThe difference in terms of the old and new spec is that instead of a piece of coursework, which they have removed, but as far as I am aware this spec deals with one open book and one closed book exam where you pick whether you do Aspects of Tragedy or Aspects of Comedy. For this specific AS you'll have to study One Shakespeare play, one further drama text (I am guessing that means another play) , One poetry text from the poets: Thomas Hardy, John Keats or one poem found in the Anthology, one prose (The Great Gatsby, Tess D'urbervilles etc). The rest is explained in the link I attached to your response. The texts that you choose from are not much different from the old spec, although very limited in comparison to what it was previously in the old one.
The A2 element of this spec does include a piece of coursework (which I think makes such a difference to your grade!) where you do two essays (this is not much different in comparison to the old spec one), this was my favourite part of A2 to be entirely honest.
As for the new spec for English Lit A I am not entirely sure how it is for obvious reasons but I would definitely look at each specification to see where you would best work, independently since you are resitting AS.
Here is the link for the specification:
http://filestore.aqa.org.uk/resources/english/specifications/AQA-7711-7712-SP-2015-V1-0.PDFAfter looking at them both myself I think that Lit B offers a bit more flexibility in terms of what genre to study whereas Lit A offers just one genre, Love through the ages.
By any chance as a private candidate are you aware of whether the centre you have chosen do the old specification examinations? As some students have the options to retake A2 year and AQA will definitely will be running the exam series of the old specs one last time see if they have given you the option to pick between the two. Although I would advise against doing AS and A2 as you need a bit of space to develop your writing (which without a doubt you will do so). I would go for Lit B as I am more familiar and I think there is a lot more options, to see where you fit in terms of what you were previously taught at AS.
Hopefully I have been of some help, I would definitely check them out and see where you fit.
If you have the chance, ask the centre their opinion regarding these two specifications, maybe they might be of help.
Best of wishes for everything! If you have any more questions do let me know!
Oh I almost forgot, you could check out some of the forums regarding both specs on tsr, I am sure they will be helpful, especially for the new specifications
