7/11 disappointment

got a 496 (121/124/125/126) on my attempt. way WAY below what i was averaging for my practice full lengths. i’m feeling really disheartened. i felt like i worked as hard as i could on this attempt and i don’t know what to change to do it again. i completely bombed c/p and my cars score is 4-5 points lower than my average. could use some advice on how to better study and/or what to do next
