New spec Edexcel A level Maths

Hey, have any of you by any chance got the Edexcel new spec Specimen papers that are locked on the Edexcel website?
Because i have a maths test next week and am currently miserably failing even tho i have done all the past papers or sample papers available lol so i was wondering if anyone had the Specimen one as it s the only one i haven't done?

I hate to not answer questions directly in general, but how exactly are you failing and is it something that can be remedied by using the textbook, rather than a new set of questions that may just have the same results as any other papers you may have done?
