Personally I would recommend you do the course at college, they are around 1 evening a week for 10 weeks. Anyone can exam cram and pass if you work hard enough, if you just want the qualification and your not bothered whether you can do the job properly or not then I would suggest doing the 4 day course. If you want to be able to do the job properly afterwards then these things take time to learn and for all the information to sink in, you'll have lots of questions over the course of 10weeks you'll want answered which many of them you would not think about if you did a 4 day course.
