ArmyBoy,
I did my TQ3 in 1989 so things may have changed a bit there! Still, I know some of the instructors there now and I don‘t believe its that much different. You will live in barracks and march to class each day with your course. You may march to class with another course if one is going on at the time (TQ5, french, etc.). You will be in classes such as common hand tools (LOL), metal working, electrical, hydraulics, etc., (basic courses) and trades courses such as small arms (C7, 8, 9, Carl G, pistols, revolvers, sniper rifle,etc). Then armament section: cougar, grizzly turrets, artillery guns, etc. You will do hands on classes (stripping/assembly/repair) and lecture (memorization of technical info). The course is six months long and if you enjoy doing mechanical work, taking things apart and troubleshooting problems you will enjoy it. Be prepared for a lowering of standards in regards to conduct and PT, etc. in Borden from what may happen in basic training.
I enjoyed the course. It was alot of fun and interesting most of the time. I was top student on my course. Although its a military course the instructors are there to help you. You can ask them for extra help if required but its best to do the work on your own if possible. You will have a bit of homework and you will have to study for exams (PO‘s)as per any course. We also had required PT classes which were lame such as water polo and badminton. You had to go but continue to PT on your own. You will have harder PT when you get to your unit (usually). We did no PT with our instructors.
Once posted you will begin your QL4 program which is an OJT program and done at the unit. You will be responsible for doing work orders just like anyone else and eventually you will have things signed off from your OJT book. Once you are finished that book you are "4"s qualified and will be put on the list for your QL5 course where you will return to Borden and do your "3"s all over again only in more depth. Once completed, you will be able to work on your own with no supervision and run a shop, for example. There may be certain things at your unit you will have difficulty signing off; these are usually signed off anyway (for example, I was asked if I had worked on any hydraulic equipment. Upon answering "no" they asked me if I had ever had my hands in hydraulic fluid. I said "yes" and it was signed off. LOL
Hope this helps you. If you have anymore questions just ask.
