1. Class sizes are much smaller than in other areas such as engineering or computer science. For example, class sizes of less than 10 students are typical after 1st year.

3. The skills taught are portable and applicable to a wide range of jobs.

The unemployment rate for a physical science professional is less than the unemployment rate for computer programmers and engineers while the pay is comparable. For a physical science professional, the Government of Canada, at its Job Futures website, states "You're more likely to find employment if your field of study is physics, geology or biochemistry."
Students with B.Sc. degrees find employment in a large variety of areas as researchers working with technology, computer consultants, oil pipeline specialists, planetarium and science centre directors, and more. Here's the story of someone who became a Forensic Physicist. Some B.Sc. graduates train to be high school science teachers while others become journalists like Ivan Semeniuk @Discovery.ca.
