dont worry
I felt the same about the first quiz, its meant to give u a feel for whats to come, and as the weeks pass u'll become accustomed to Dr. Kim's methods of trickery. Also remember that he drops the 2 lowest quizzes.
Mastercool, keep up with what ur doing now, u have the right idea, once u get the feel for things u'll be fine.
Just to add: i did this course as a lone wolf, mainly coz i commute and i did perfectly fine
So dont lose hope!
