Enter each Grade 11 and 12 course with its mark, type (U, M, C or O) and credit weight. The calculator picks your six best University or Mixed courses, shows which marks count, and compares your average with the typical admission range at the universities you choose. No account is needed and your marks stay in your browser.

How the Best 6 is calculated

  1. Only Grade 12 University (U) and University/College (M) courses are eligible. College (C) and Open (O) courses are left out.
  2. Your six highest eligible marks are averaged. Half-credit courses count for half as much.
  3. If a program requires a course, that course must be one of the six, even when another mark is higher.
  4. Until your Grade 12 marks exist, universities look at your Grade 11 U/M marks for early offers.

Common questions

What is the Best 6 (top six) average?

Ontario universities calculate your admission average from your six best Grade 12 University (U) or University/College (M) courses, including any prerequisites the program requires. Marks in other courses are not counted.

Do Grade 11 marks count?

Final offers are based on Grade 12 U/M courses. Grade 11 marks matter for early offers, which are made before most Grade 12 marks exist, so a strong Grade 11 top six helps you get an offer sooner.

Do College (C) or Open (O) courses count?

No. Only University (U) and University/College (M) courses are used. This calculator ignores C and O courses when it picks your top six.

Does a prerequisite have to be in my top six?

Yes. If a program requires a course such as Calculus or English, that course is included in your six even if another mark is higher. Check each program's required courses.
