Maximum drawdown

For L1 my scores were quite close to each other, here I see them flopping up and down. Fortunelately, a regression would should that they are upward sloping but the standard deviation is HUGE.

I have been from a high of 87 to a low of 53 (only 30 questions, but still)

i have a mean reverting level of 65, with highs of 70 and lows of 59
