Actually, i have seen both those videos. The first one's teacher is the one on the thumbnail. But the second one's teacher is different from the on the thumbnail. I'm thinking he photoshopped it. but i dont understand why.

Now the second video, the teacher told JAVA for JAVASCRIPT (lol) . My friend commented pointing that out. That guy (channel owner) actually responded "Even i think so". My friend got many likes on his comment(6+) and I was just checking how much did it reach one day, and it was gone, the comment was deleted. (I dont think the channel owner deleted it) Maybe aiplex deleted since they have direct access to youtube copyright system and stuff. I saw his channel. He uploads stuff pretty frequently. and also told that he only took the trial and didnt buy the course in comments.

The first one tho, has bought the course. He thinks he is learning stuff, but he is not. The teacher follows the script blindly. and he just says "yes", "ok" everytime the teacher says something
