Chance me/ help?

I am a Canadian Asian female. My average was around 93 to 95 for grade 9 and 10. And I took the most challenging courses my school was able to offer. However, grade 11 had been he** for me. Like usual, I took all of the hardest courses my school offers, but covid and family stuff had been a lot. Now I am sitting at a 55% average for the first semester. My dream was to get accepted by an Ivy, so would there still be a possibility for me?

I am taking the SAT and the subject tests in May. I’ll probably get somewhere around a 1400.
