4.0 

A Bachelor of Health Sciences Student at McMaster University in Hamilton, Ontario, Canada.

Currently resides in Mary E. Keyes Residence.

His ideals are reflected by his relentless pursuit of a perfect GPA: a 4.0, so to speak.

The man would give up anything and everything for a 4.0, including all extracurricular endeavors and sex life (or lack thereof).

When asked "How would you like to go on a date with me?"

4.0 answered, "I'm sorry, I cannot do that since I must focus on my studies."
