September
Check in with your counselor about taking the PSAT as a sophomore. If you will be taking it, find out how (and if) you want to prepare. Your PSAT score doesn't mean much this year, but you still want to do your best, if only to give you confidence for next year.
To Do:
Get to know your teachers—you probably won't have any of the same ones from last year.
Take note of any major assignments.
Register for the PSAT if you need to. Your counselor should have information about this.
