Seeing as it's quite a new unit, I'm sure it'll improve. Unfortunately, it seemed quite disorganised. I stopped showing up to the workshops, as most of what was covered in the first couple of them seemed very basic. It's probably good if you have no real experience with Excel, though. I did and got quite bored, as the functions etc. covered were functions that I was already very familiar with. If you do have experience with Excel, it should be an easy HD.
