How about don't do it!!! Not all its cracked up to be and more cash in your pocket maintaining the trains!!! But if you insist.....try a Kingston Course for the Foundation Degree and in 2 years have all the modules....then need to get an employer......but can be done and is done....... You just need the time and cash to do the course....I have seen a few who have done it in their 40's....beats me why though....
