OCR Application Deadlines

Hey guys,

I go to a West Coast Target / Semi-Target with OCR.

Just had a question about the typical timeline for resume drops and on-campus interviews. Tried searching, but couldn't find much.
Are most resume drop deadlines around late-December? Trying to see how long I have to raise my GPA as high as I can and use my hopefully higher GPA after Fall semester.

Thanks a lot
