I agee 100% with this comment,these short courses are a joke,sorry if this upsets anyone but there is a reason why courses are done over a length of time,it's because they are designed to cover all areas of the chosen subject,A&P,methods,health and safety not to mention a host of other things.
Yet people still insist that they can do what some of us have taken months even years to do,in as little as a couple of days.
My thoughts on short courses will always be the same,also it never ceases to amaze me when people say,"well I studied really hard on my 3 day course",yes,I'm sure they did but nowhere near as hard as any of us that studied the same subject over months and months,even years.
If you really want to learn a skill do it properly,over a period of time,as it was designed to be learnt.Do it this way so you know what you're doing,so that you're confident and so that you can really call yourself qualified.So you know your subject inside out and only need to pick up speed.So you can answer clients questions freely without doubting yourself,and also so you can hold your head up high when discussing your qualifications.
Sorry if this offends but there are too many short courses and I have tried both,only twice did I do a short course and both courses I re-did the proper way, because I found there really is no comparison.I didn't feel truely confident and tbh felt a fraud when asked by clients about my training in these 2 areas.JMHO.
