I have done that C & G course. The certificate is valid all over the world. To attend to a job it is valid, or to migrate to another country it is valid. But no more practical experience I have gained from it. I got some few electronic knowledge from that course.
I learned much more about electronics not from courses. It’s from what I did at home.
Making circuits, Measuring, burning etc…..
For my practical exams these were involved
Biasing a transistor, simple opamp-measuring the gain etc…oscilloscope practice…reading resistor values …some times 555 calculation’s.
All the circuits done in the breadboards. No soldering practice. for the computer project there was some small access database. It’s very easy.
I would like to know how much practical work is involved, would you be able to repair TV's etc.. at the end of the course?
Don’t even think about it. If you want to repair TV’s better go for a TV repair course. Nothing teached about TV’s.
The course was all the time with transistor biasing, Some small op amp calculation’s & some small digital gate circuits. In electrical subject - types of Motors, AC line calculation’s etc.
C & G course 400 US$-no experience in practical but valid all over the world.
TV course 60 US$-all the time with practical.
