hi judebi
i am even older than you (!!) and have applied for the 4-yr courses at St George's, King's and Queen Mary's & Barts, so go for it! check out also the parents at med school forum on this website.
note that queen mary's also require MSAT (like Kings) but are apparently changing to the UKCAT in 2007. you need to check this out with the college itself.
i recommend the following books:
(1) "the insider's guide to uk medical schools" eds j burgess, s girgis & k hebert
(2) "how to get into graduate entry medicine" by d sellars & y knight.
i have a science background, but still needed to do a lot of revision for the gamsat. i have the des o'neill notes, which i found very useful. the promed are ok but have big gaps in the information. the gradmed tests and the ozimed tests are good practice for later on (check ebay). you must get a copy of the official acer test papers, though, if you are serious about the gamsat. you will also need good a-level biology, chemistry and physics books. for your final revision, the lett's revise in a week series are good. in theory if you start your science now you should be able to sit the exam in september, so don't loose hope!
pm if you need more info.
good luck!
