Do what others have done in your situation:
speak to the teacher in advance regarding your dilemma and if the teacher can prepare in advance extra stimulating work for you…
even if you begin with other meforshim followed by Nechama Leibovitz or categorizing different topics or comparing similar root words with different meanings or even working with a girl struggling with the subject…or the teacher can create her own workbook for you…
just remember to thank Hashem for the gift and not let others feel bad
