# First-Year Courses

Below, you will find suggestions about the courses you should take based on your area of interest. FAQ's are listed at the bottom of the page. You can click on the program titles to be taken to the list of modules available in that area and view all of the required courses.

### General Guidance

- Students may not take more than 5.0 courses in first-year. Students must take a minimum of 1.0 first-year elective course(s) that is non-science.
- If you have IB or AP credit that is non-science, the non-science first-year requirement has been met.
- Western Scholars: Consider signing up if you have at least a 90% final admission average.

### Unsure of what you want to do?

Keep your options open as much as possible! Many first year courses are offered in the summer if you realize you need something else for the module you want in year 2. Yes, you can change your mind after first year and switch to a different module!

### Considering an Ivey Dual Degree?

Students interested in or considering a **combined degree with IVEY** are strongly encouraged to take their 1.0 first year course from **Category B** to avoid having to overload or take it in the summer. BUS 2257 will count as Category A.

### Advanced Standing Credit Advice:

- A degree requires a minimum of 5.0 first year courses. Advanced standing courses count towards this requirement.
- Students may repeat an advanced standing course(s) OR take a combination of first year courses and senior level courses. If they repeat an advanced standing credit, the IB or AP advanced standing transfer credit will be lost.
- If students receive advanced standings for prerequisite courses such as Biology, Chemistry, Mathematics, and/or Physics, and choose not to repeat any of those advanced standing credits, they may take module courses (2000 level) that have those courses as prerequisites. This will mean that their course load will have some first year requirements (could be required first year prerequisites and/or electives) and some module courses.
- If admitted with 3.0 advanced standing credits or more, students will be considered as second year. Transfer credits may satisfy breadth but no essay requirements.

### Frequently Asked Questions

### Can a student take a 0.5 course in Category A and a 0.5 course in Category B in first year?

Yes. The Faculty of Science allows this combination, as well as a full 1.0 course in one of the two categories. However, this may also limit a student’s choice in terms of module and course selection in year 2, should they change faculties.

### Should Science/Medical Sciences students take an essay course in first year?

Students should be advised to select option courses that are of particular interest to them, based on previous experience – not on the basis of whether the course is an essay course or not. Many modules have essay course built in.

### What are the implications for a student who decides not to take any Calculus in first year?

The student will be limiting his/her module choices as at least a 0.5 Calculus is required for most modules in Science and Basic Medical Sciences.

### Can a Science/Medical Sciences student take a course at an Affiliated University College?

All students at Western, including those in the Faculty of Science, can take 1.0 course at one of the Affiliated University Colleges per session, provided the course is not offered on main campus.

### What constitutes a ‘subject area’ in Science, to ensure a student has 4 different areas and no more than 2.0 courses in each?

Actuarial Science; Astronomy; Biology; Chemistry; Computer Science; Earth Sciences; Environmental Sciences; Physics; Statistical Sciences – are all separate subject areas. Courses in Applied Mathematics, Calculus and Mathematics belong to the same subject area – the subject area of mathematics.
