Heavy on the theory, very little practical and brain was leaking out of my ears by the end of day 2. Like all these things theory only goes so far. After the course bought a system and installed it in my house which helped get a better understanding also.
Yes System Q are great i did the two day course a couple of years ago the courses were good and full of info but did asume that you knew how to terminate ect already. Cost me
wouldent bother unless your doing large scale IP jobbys. ive just learned as ive gone along, im into photography so i knew what specs to look out for but you can just google that any way. recently done a local small industrial estate/ group of units. good moneys!
