An on line resource may be useful for returning students. Access courses should go some way to preparing students for HE. I think maybe some additional training for teachers who teach matures, as at my college there is varying standards of teaching from our tutors. Some of the people on my course are lacking in skills and confidence, as a result this holds some of the rest of us back. This is where the tutors need to be made aware of varying skills and then take this in to account when planning work.
So all in all I think something that students can use along side their study, a resource that shows them how to lay out an essay, use applications such as power point (even word in some cases!) As for me these are the things that are slowing us down much of the lesson is spent explaining these things to some of the group, which aside from being time consuming, is actually irritating! It would be good if these students had somewhere online to look this stuff up.
