Degrees vs Majors
A degree is the overall area of study you are completing. This could be something like a Bachelor of Science, a Bachelor of Arts, Bachelor of Commerce etc. You may see contractions of them, such as B. Sci, B. A., B. Comm, but they mean the same thing as the full version. A major is the subject area within your degree that you specialise in. For example, you may be completing a Science degree, but focussing on Psychology as your major, which would make it Bachelor of Science (Psychology), or B. Sci (Psych) in contracted form. Depending on the requirements for a major (this varies from uni to uni), you may be able to complete two majors within a single degree.
Some people complete a double degree, and have a different major in each degree. This can get confusing but in the case that someone completes a double degree in Science and Commerce, with majors in psychology and finance, it would look like Bachelor of Science (Psychology)/Bachelor of Commerce (Finance), or B. Sci (Psych)/B. Comm (Fin). Just a word of advice, always have a look at what majors are offered in your degree. In the end, a prospective employer will not so much look at the degree you completed but rather the majors you completed in that degree. For example, if you compare a double major in marketing and HR against a double major in accounting and finance, both of those students will graduate with a B. Comm but one is theoretically more useful in a particular field. Also if you don’t get into your favoured degree, see if there’s another degree which runs the same major/s you want to complete.
