there is a special place in heaven for you sir,
ive downloaded the full playlist and im revising physics for the next few months hopefully getting a seven.

Hello! First of all thank you so much for making these videos! They are really helping me with SL Physics. I've got a question, the other day I was solving May 2013 SL Physics Time zone 2 paper 2 and in the first question there was a graph with error bars [V(potential difference) vs Time] which goes down with a curve when connected (decreasing). And it wanted the "best fit line for the data starting from t=0" of that graph so I drew a straight line starting from (0, 0) but the answer was actually connecting the error bars and having that curve for an answer. I'm so confused about what to do when the best-fit line is asked, please help!!!

"at least I'm measuring them equally wrong" 😂😂
