hey there!
i was in the same situation last year! at around this point in time, we were up to chapter 4 and other schools had almost finished chapter 7!
the best advice i could give you is to try and get ahead (not by too much, you don't want to skip vital information for the course or forget anything). i did this last year and it helped me a lot. while other students were cramming in chapter 6 before our exam, i had already done chapter 6 and chpater 7 (which we didn't do) and felt really confident for my exams. this is because it gave me time to nut out a lot of practice questions! also, another major disadvantage because of this was that we didn't finish calculus last year because my school was far too behind - getting ahead helped me because calculus at times can be tricky, so having enough practice helped me a lot!
but honestly, dont stress - because just like your school, even my school is behind.
if you would like more resources to help you out, check out NancyPi on youtube - or even khan academy!! these vidoes helped me out a lot considering how far behind we were. For example, my class was preparing for exams but I stared preparing months in advanced so I decided that I would do some intergration problems (we didn't even do intergration in class because we didn't finish the course). Basically, the question wasn't difficult but I didn't like how my answers for the area were negative. I went on youtube and learnt about modulus functions and then i was able to fix my answers!! youtube is such a great resource!!
best of luck with everything though,
i'm sure you'll do great!
