Good luck, I did two evening VTCT courses last year Indian Head and Reflexology. I managed to do this whilst holding down a fulltime job and looking after my OH and son.
The college was very encouraging and very supportive. The A & P was very interesting and I was able to merge the A & P so one evening a week I went in later than the others which was helpful. But I digress, I wish I could have done the fulltime course
As for age dont worry, we were a mixed bunch, on the whole mature students, even a couple of pensioners but we all supported each other and helped each other. I'm now 47 and last studied at college 30 years ago (the same college), keep up with the homework, organise your time so you can get the practical work done. I found it easier to use the same people for my practical work and they were very responsive as they had an IHM and then reflex.
As for books ask the tutors, they tend to have a fav book that they recommend. For the A & P I found pocket version which was recommended for nurses.
Good luck and dont worry, enjoy the course the lecturers will guide you through the various segments, explaining each bit as they go.
Have fun
