Ontario OSSD Credit Courses
OSSD isn't hard — most students start with the wrong plan. We do three things: get you ahead, fill gaps, lift your Top 6.

How we plan your Top 6
STEP 01
Assess current state
Existing credits, transcript, target majors — assess 4 dimensions and produce a baseline report.
STEP 02
Reverse-engineer Top 6
Work back from target programs to required Top 6 courses, prioritize, sequence.
STEP 03
Build the calendar
Mix semester + summer + winter terms, balance public-school load, no conflicts.
STEP 04
Track ongoing grades
Biweekly parent check-in, early-warning on slip risk, adjust pace as needed.
