I found the Met course helpful
I went on one at Bracknell some years ago and found it very helpful indeed, and as a result feel much more at ease in decoding synoptic charts and looking at forecasts with a critical eye. I also learned from experts about what sources of information were available to enable a safe flight. Clearly things are different now with the internet but the experts are still likely to be one step ahead of the rest of us. As I had a VMC only aircraft at the time, that knowledge was very important and added enjoyment (through extra confidence) to my flying. I guess that what suits one person doesn't suit another. I suggest you find out the syllabus and see whether you have gaps in your knowledge on the bits to be taught and take the plunge if you do. The worst that can happen is that you waste your money - but I defy anyone to go and learn absolutely nothing.
