11th backlogs (HELP)

So I am a PCMB student, and since oct/sept last week I have not been in class. Like not even for a single period, as I had to train for my extracurriculars for a competition (proudly got 3rd tho😝) however due to this I've missed my vital classes, I thought that I would stay back in school and ask some of the teachers for help (which they kindly agreed to) but unfortunately I got hit with dengue 😭

Now I am sick with a high fever, tired with backpain and a ton and I mean a ton of BACKLOGS. oh and btw we have finals on jan. what should i do?!? how should i start?!? pls help me guys 😭🙏
