Stupid annoying implicit differentiation

I have never encountered maths so annoying in my life before. I was doing stupid, stupid implicit differentiation on Khan Academy. I have wrestled with the topic for more than three days and still I cannot pass the practice session which requires you to get at least 5 correct in a row. Although this sounds very reasonable, I find it very demanding. It's not that I don't understand the topic, but everytime, it's just that minus sign, a Y that I forgot to sub in the value,  or forget that I need to sub in the values which cost me that last crucial question. Arrrrhhhhhhhhhhh quoting Sheldon "I feel like I want to peel off my own face and tear it in two and then again and again until I have a handful of Sheldon-face confetti."

Looking on the bright side, I would probably get the Persistence badge which is awarded as you "Answer a problem correctly after having some trouble with a few problems and sticking with the skill"

Right, some trouble.

Edit: Then I saw this:

I spent nearly 2.5 hour doing all the questions and still can't get it right. FML.

Edit edit: I just realised my first post in a new year is such a negative one. Oops.

Edit Edit Edit + newest update:

Yay I finally tackled implicit differentiation! It was a fine, normal day; I was bored so I went back to do the questions, did five correctly on the first try and passed.

Actually sometimes all I need is to chill.

And damn, they didn't give me the persistence badge!!!
