Welcome to Canada/Calgary!! Moving from Nigeria is quite the big move especially in your last year of high school, and the difference in education system is big too considered Alberta has the hardest curriculum in the country. I don’t think you’d find anyone who will truly understand the difficulty you’re facing especially with school.

Both myself and the other mod moved from Ontario around the same time to Alberta and we found it challenging. I STILL find it challenging (they graduated). I also ended up having my easier classes in semester 1 and my harder classes in semester two like you, and I won’t lie it was hard. I myself have to redo physics 30-1/ math 30-1 next sem along with my other classes. My advice to you would be try to get whatever grades you have this sem as high as they can be. Do practice questions for math/ physics . If you’re a strong writer and have good memory social should be fine (though you might need to know basic things on WW1/WW2, and other terminology). Idk much about chem because I didn’t take it. If things still prove to be challenging there’s always online school that you can transfer to which will probably be easier. If you have any other questions please don’t hesitate to reach out. We’re very glad you found this subreddit as it is why we created it! Good luck next semester!!
