is MY instructor ripping me off?

saw a post about the pace someone else was going on here and lmao it made me realise my instructor hasn't done quite a few things with me. i pointed out to him that he still hasn't brought up reversing around the 28 hr mark and in the next lesson, he asked me to pull up on the right and reverse 2 car lengths. that was my first time ever doing it. we're at 31 hours now and nothing since. is that unusual? should i mention it again? i feel like its weird that i dont know how to reverse at 31 hours of lessons (not including the first 4 i had with a 0/10 instructor). maybe he forgot? idk
