    Its a great refresher course. Within a few days i was already at level-10, Howerver, i knew some of the anwsers were incorrect, like has been stated by many.I wonder if hes really certifyed ? And for beginners learning this feild be careful of what youre listening to. Because as stated, you go out and work on someones unit with the wrong information it could cost you hugely 👋

    Do not use to gain knowledge, as the creator certainly had very little. Says compressor changes high pressure liquid to high pressure gas... I don't know what compressors he's working on, but it won't be mine.

    Some questions are unheard to me, if any wrong answer there should be explanation although there is a option to send the feedback, overall it is great experience.

    Sorry guys, but current decreases if voltage decreases and resistance is constant,,, this question came up a few times and is pretty basic knowledge... doing people who are just learning this material a huge disservice... proof read your info.
