stanford online high school admissions 2021

hello!

so i’m looking to apply to stanford online high school for the 2021-2022 school year full time. it would be my junior year. i’ve never had below a 95 in a class.

here’s my problem. since i’m homeschooled, i do two grades a year so i don’t know what to submit. i would only have tenth grade completed a little. should i still submit what i have done for that? or just submit 8th and 9th.

also, what do you think about taking the SAT this year because of the virus? i could take tests like the IOWA and the COGAT which you can purchase and do at home.
