Credit upgrading

Raise your average. Open more doors.

A few percentage points can be the difference between an offer and a waitlist. Retake a Grade 11 or 12 course in a small class with a teacher who makes time for you — and we'll make sure your new mark reaches your applications.

How upgrading works

Your best mark is the one that counts.

When you repeat a course, universities and colleges typically consider your highest mark — check each program's policy.
  1. 1

    Pick the course

    Choose the Grade 11 or 12 course you want to improve — often MHF4U, MCV4U, SCH4U, SBI4U or ENG4U.
  2. 2

    Choose your schedule

    Full-time, evenings and weekends, summer school or online. Fast-track options let you finish in as little as a month.
  3. 3

    Learn it properly

    Small classes, a personalized teaching plan and teachers who explain until it clicks.
  4. 4

    Send your new mark

    Tell us where you've applied and we'll make sure your final mark is reported to OUAC or OCAS.

Why students upgrade with us

Focused teaching beats a crowded classroom.

Students tell us the difference is time: our teachers spend 30 to 45 minutes making sure you understand a concept before moving on. With only two courses per term — or one in summer — you can give the course that matters most your full attention.

Most-upgraded courses

University prerequisites we teach most

  • MHF4UUniversity

    Advanced Functions

    Grade 12 · Mathematics

    This course extends students’ experience with functions. Students will investigate the properties of polynomial, rational, logarithmic, and trigonometric functions; develop techniques for combining functions; broaden their understanding of rates of change; and develop facility in applying these concepts and skills. Students will also refine their use of the mathematical processes necessary for success in senior mathematics. This course is intended both for students taking the Calculus and Vectors course as a prerequisite for a university program and for those wishing to consolidate their understanding of mathematics before proceeding to any one of a variety of university programs.

    Prereq: MCR3U / MCT4C
  • MCV4UUniversity

    Calculus and Vectors

    Grade 12 · Mathematics

    This course builds on students’ previous experience with functions and their developing understanding of rates of change. Students will solve problems involving geometric and algebraic representations of vectors and representations of lines and planes in three dimensional space; broaden their understanding of rates of change to include the derivatives of polynomial, sinusoidal, exponential, rational, and radical functions; and apply these concepts and skills to the modelling of real-world relationships. Students will also refine their use of the mathematical processes necessary for success in senior mathematics. This course is intended for students who choose to pursue careers in fields such as science, engineering, economics, and some areas of business, including those students who will be required to take a university-level calculus, linear algebra, or physics course.

    Prereq: MHF4U
  • SCH4UUniversity

    Chemistry

    Grade 12 · Science

    This course enables students to deepen their understanding of chemistry through the study of organic chemistry, the structure and properties of matter, energy changes and rates of reaction, equilibrium in chemical systems, and electrochemistry. Students will further develop their problem-solving and investigation skills as they investigate chemical processes, and will refine their ability to communicate scientific information. Emphasis will be placed on the importance of chemistry in everyday life and on evaluating the impact of chemical technology on the environment.

    Prereq: SCH3U
  • SBI4UUniversity

    Biology

    Grade 12 · Science

    This course provides students with the opportunity for in-depth study of the concepts and processes that occur in biological systems. Students will study theory and conduct investigations in the areas of biochemistry, metabolic processes, molecular genetics, homeostasis, and population dynamics. Emphasis will be placed on the achievement of detailed knowledge and the refinement of skills needed for further study in various branches of the life sciences and related fields.

    Prereq: SBI3U
  • SPH4UUniversity

    Physics

    Grade 12 · Science

    This course enables students to deepen their understanding of physics concepts and theories. Students will continue their exploration of energy transformations and the forces that affect motion, and will investigate electrical, gravitational, and magnetic fields and electromagnetic radiation. Students will also explore the wave nature of light, quantum mechanics, and special relativity. They will further develop their scientific investigation skills, learning, for example, how to analyse, qualitatively and quantitatively, data related to a variety of physics concepts and principles. Students will also consider the impact of technological applications of physics on society and the environment.

    Prereq: SPH3U
  • ENG4UUniversity

    English

    Grade 12 · English

    This course emphasizes the consolidation of the literacy, communication, and critical and creative thinking skills necessary for success in academic and daily life. Students will analyse a range of challenging literary texts from various periods, countries, and cultures; interpret and evaluate informational and graphic texts; and create oral, written, and media texts in a variety of forms. An important focus will be on using academic language coherently and confidently, selecting the reading strategies best suited to particular texts and particular purposes for reading, and developing greater control in writing. The course is intended to prepare students for university, college, or the workplace.

FAQ

Upgrading questions.

See all questions
Are Innocent Hearts credits recognized by universities and colleges?

Yes. Innocent Hearts is a private secondary school inspected by the Ontario Ministry of Education (BSID 886638). Every credit you earn here — in class or online — counts toward your Ontario Secondary School Diploma (OSSD) and appears on your Ontario Student Transcript, which universities and colleges accept.

Can I take a course while attending my regular high school?

Absolutely. Many of our students take a night-school, weekend, summer or online course to get ahead, free up their timetable or improve a mark — and we send the final mark to their home school.

Will you update my university or college application with my new mark?

Yes. Tell us which applications you've made (OUAC for university, OCAS for college) when you enrol and we'll make sure your final mark is reported.
