I wish you were my teacher! This is actually making sense and believe me I thought I was a lost cause!! THANK YOU!!

[para143]

I loveee you..your the bestt!!

@bromance999 - He has over 80 of these and 10 minutes each is like 20 class days if you only have 40 minutes per class.

[Angelgrrl04]

Too bad you couldn't just teach how you got those numbers in this video. With you just popping up numbers like it's given, is 0% useful.

Thanks so much! : )

[shoshikun]

you are a beautiful man.

[sm9453]

oh my god I never ever understood this. it's JANUARY. we learned this in OCTOBER. my midterm's this week and man, I really have to owe it to you for finally getting me to understand this! seemingly simple, but it leaves you so confused when a teacher doesn't know how to convey the message clearly to his/her students. thank you so much!!

[llamafulloshit]

MIND FREAKING BLOWN. I haven't understood this for 4 months. I literally learned more in the first minute than my teacher taught me in 4 months.

[Jasaxos]

Ugh my teacher already expected us to know this so she skimmed through it

I learnt trig( not really 2 yrs ago so I was like huh?

Many thanks

kan eg få stille et spørsmål?

[Darkmaxmuk]

My physics teacher sucks, i wish u went to my school...

PANAMA: ISP

lol why am i saying this...
