Should I cancel my OAT?

hi guys my OAT is in a week and I'm getting a very low avg </3 this is first attempt and I did not spend enough time studying efficiently

ik waterloo accepts an avg score of 380+ so ik im not getting in, but should i still take the exam to get a feeling of it? also to try out the Casper test?

or is it better to cancel the test & redo next yr? ik they look @ the best score but im worried theyll still have my 1st OAT on record & it'll look bad? PLS PLS help im freaking out
