Dear @julygirl458,
You are in Grade 9- so, 14? The next 3 years are long. You will (or should!) do all kinds of growing and changing during that time. As it turns out, so will the world.
Please read this: https://mitadmissions.org/blogs/entry/applying_sideways/
Then re-read it.
Then tell the part of you that says “that doesn’t apply to me because of reason X or Y’” that it is wrong.
Read it, believe it, live it- and come back in 2 years and let us know how it’s going!
