You dont have awful grades at all. Go test optional to schools that allow it.
Questbridge, a (full four year scholarship) deadline is in two days. You mentioned you have been working on essays so if your essays are done, you may be able to complete the app in time. The scholarship app IS your college app, so make sure its your best. You also may be able to reach out to them to get an extension. LOR can be received after the deadline as long as you applied.
