Dr. Jess ๐ completely normal. if you know you tried your best, i wouldnโt be mad. people can understand information easier than others, and Bs are still really good. you shouldnโt undermine yourself or your performance, nor feel inclined to tell others your score- something i donโt do very often either.
i would continue trying my best, and if you want to get that extra 5-10%, ask your teacher what you can do to get there. theyโre there to help you, not wish you the worse.
being the best is nice, but doing your best is better for your mental wellbeing ๐
