You both missed the point I was trying to make.If a computer tech was known to me, that's a different story.
If you rang someone out of the paper I would like to know if he was trained or self trained.
I wouldn't like just anybody using my expensive computer as a dummy so he could learn on my computer with trial and error.
I still think if Mike just learning to repair computers it would be a positive doing some course to further increase his knowledge so he would have both theory and practical experience at the same time and learn quicker.
I didn't do a course and I fix my own computers and I give them what for, believe me.
If I was repairing computers for a living then I would increase my knowledge further.
