The UBC Real Estate Club is the resource I most often use to learn from and link to alumni who are making the biggest impact in their industry. The faculty are primarily made up of students who are eager to help those around them.

My personal favorite resources at the moment is the Urban Land Institute, for its abundance of young professionals and casual events designed to educate new professionals.
