Guys, I appeared for physics 33 a couple of weeks ago. The paper was extremely approachable but out of the blue, I made a very, very stupid mistake. I took the time for 10 oscillations and likewise took 10 readings; however, I don't know why but I forgot to divide the time taken for 10 oscillation by 10. As a result, my y-axis values, gradient and y-intercept are all up by a factor of 10. Had I corrected my readings, my gradient and y-intercept would've been in the range of values expected. How many marks I might lose for the error I made? I am already losing 1 mark in the second question, and 2 marks in graph plotting. How much more? Anyone?
