Wondering if we look at Grade 11 marks, if it matters where you rank Waterloo on your application, or when you might receive an offer of admission? Check below for commonly asked questions.
Admission averages and requirements
What are Waterloo’s admission averages?
Waterloo’s admission averages range from high 70s to mid-90s. Admission averages can vary depending on the number of applications we receive, the number of spaces available in each program, and the grades of students who apply.
Smaller or highly competitive programs will have higher admission ranges. Search our admission requirements to see specific admission averages.
What average do I actually need?
Admission averages are influenced by the number of students applying to a particular program, their overall average and grades in required courses, and available spaces in a particular program.
We don’t under or overestimate the admission ranges we publish. They’re always based on the students we admitted the previous year and what we expect the average to be for the current year.
For programs that have supplementary requirements such as interviews or a portfolio, those factors are in addition to your grades and influence admission decisions.
Do you look at Grade 11 marks?
For many programs, we can use Grade 11 marks and mid-term or predicted grades for your Grade 12 courses to make a conditional offer of admission. Your Offer of Admission would list the conditions you need to meet, i.e., the final grades you’ll need to achieve.
If your Grade 11 marks aren’t as high as you’d like them to be, we'll use your Grade 12 grades when we make our admission decisions.
We anticipate many students' grades go up in Grade 12. You won't be disadvantaged if your Grade 11 marks aren’t in our admission range.
For highly competitive programs, we may wait until early May to make offers of admission so that we can see second semester mid-term grades, especially for required courses.
If you're applying to the School of Architecture, we use grade 11 and grade 12 grades to select students for the interview and portfolio stage of the application process.
Do I need specific extracurriculars for specific programs?
No, but many of our programs like to see examples of initiative, leadership, time management, people skills, and a range of interests and involvement.
If you’re applying to programs in the Faculty of Mathematics or to Software Engineering, you’re encouraged to participate in Waterloo’s math and computing contests.
Results of the contests will be used in scholarship decisions and possibly admission decisions for programs in the Faculty of Mathematics.
Can I repeat a course or take a course outside of regular day school?
This could affect your application depending on the program or faculty you apply to. Review Waterloo’s policy on repeated and non-day school courses for details.
Do you weigh some courses more heavily than others on the average?
We don’t weigh courses differently, but we will always include the courses which are required for admission in your admission average. We will then use your remaining courses with the highest grades to calculate your overall admission average.
If I take a spare or two, will it impact my application?
Taking one or two spares will not impact your chances of being admitted.
Application process
Does it matter how you rank Waterloo on your application?
No, it does not matter where you rank Waterloo programs on your application. At Waterloo, we examine each application equally. Please rank the Waterloo programs you're applying to based on which programs and universities are your preference.
If you apply to more than one Waterloo program, you'll receive a decision for each program, not just your top ranked Waterloo program.
Can you apply to more than one Waterloo program?
You can apply to a maximum of three programs at Waterloo except for Engineering, where you can apply to one program on your application.
If you wish to be considered for a second Engineering program at Waterloo, you can specify an alternate choice on your Admission Information Form once you've applied. Biomedical Engineering and Software Engineering are not available as alternate choices on the AIF.
For each Waterloo program you apply to, you will receive an admission decision (offer of admission or a refusal).
How do you apply for admission?
Applications to Waterloo and all other Ontario universities are handled by the Ontario Universities’ Application Centre (OUAC).
Applying through the OUAC means you can apply to multiple Ontario universities with a single application, saving you time.
How do you apply to co-op?
You need to select the co-op option on your application to be considered for a co-op program.
Where a program is offered through co-op and the regular system of study, if you apply to co-op and are not admitted, you may be considered for the regular version of that program if space is available.
If you're interested in both the co-op and regular systems of study for Health Sciences, we recommend that you apply to both streams. Due to the competitiveness of this program, we can't guarantee that if you're not offered a space in a co-op program that you'll be considered for the regular option.
How do you apply for early admission?
Waterloo does not have an 'early admissions' process. Admission decisions are made from December to May depending on the program you have applied to.
Since our admissions committees require at least mid-term grades for all required courses before decisions can be made (except for Architecture), most of our admission decisions are made in May once we receive mid-term marks from semestered high schools.
What is Waterloo's acceptance rate?
Waterloo’s acceptance rate varies by program and can vary by year. If you meet the admission requirements, you should apply.
Extra questions for Ontario students
Does Waterloo accept NBE3U (for Ontario students)?
Waterloo recognizes NBE3U (Understanding Contemporary First Nations, Métis, and Inuit Voices) as an acceptable 3U English course. Admission to Waterloo also requires the appropriate 4U English course. Please see our admissions requirements for details.
Are Ontario DU language courses (i.e. LKMDU, etc.) included in admissions averages?
Language courses taken at an institution accredited by the Ontario Ministry of Education and that have a DU level designation are considered as 4U/M courses and can be included in top 6 course averages.
I'm an Ontario high school student completing the IB program. Which admission requirements must I meet?
Ontario students completing the IB program would follow the admission requirements for Ontario high school students.
If you're applying to programs in the faculties of Engineering or Mathematics, you can indicate that you are taking IB courses on your Admission Information Form (AIF).
If you receive an offer of admission, you must have your official IB results sent directly to the University of Waterloo by the IBO to be considered for potential transfer credits.
Are Ontario high school O, C, and co-op courses included in the admission average for decision?
No, only U and M courses are included in the overall admission average.

Offers of admission
When will you receive an admission decision from Waterloo?
Admission decisions are made between January and May depending on the program and whether you’re an Ontario high school student or not.
Most offers of admission at Waterloo are made in May, once we’ve received mid-term marks from Ontario high schools. A limited number of earlier offers of admission may be made in some programs.
How do you view your offer of admission?

Do you have conditions on your offer?
Most offers of admission have conditions that need to be met by a certain date (usually over the summer). Conditions could include achieving a minimum final average or grade in a required course, submitting final transcripts, sending English language requirements, and more. By not meeting these conditions, your offer to Waterloo could be rescinded.

Normally, a deferral will only be granted if you are not undertaking post-secondary studies during the deferral period, unless those studies are deemed to enrich your education and will not negatively affect your admissibility. Please email our admissions team if you have additional questions.
