yes that is true. I'm 19 and currently doing a level 1 60 credit module in Bsc (hons) Environmental management and technology and i think its very manageable in terms of difficulty. I would say that you should have have a decent english and maths level e.g gcse or eqivalent (although maths could vary depending subject) as i think it would be of great importance on studying an English degree or any degree subject for that matter.
I would say the tutors are helpful and they do give advice and help if neccesary however i'm speaking from the experience of my tutor as others could vary but i'm pretty sure most of them are similar. Hope that helps!
