Okay, i'm glad i didn't say too much during my little rant this morning (see previous post), as i've now spoken with Masoud Sadjadi and he explained that the Kaseya 6.3 course materials will be available very soon and that they've put a lot of effort into it. (I think it's just very unfortunate for me that i've picked up on a lot of the problems they were already aware of but had not fixed - due to the new release coming out).
I cannot make any comment on whether the 6.3 materials will be any better, but it makes sense to me that if they were aware of the previous issues, they would make sure the same doesn't happen in 6.3. (And for anyone who has experienced the dodgy audio on the course materials, they've sorted this too for the next release).
Overall the course has been good and i would recommend it to anyone else wanting to do one - just don't jump on a course before they release a new version ;-)
Now i'd better go and finish swatting-up before i take my exam....
