Rotman Commerce Case Competition Team

I'm an incoming first year and I recently found out about RCCT and am super interested in joining, except I have no experience in the field.

1. What are some things I can do to prepare and increase my chances of getting in?

2. Is there any way I can practice case competitions before the application process begins?

3. What opportunities are there to improve at public speaking?

4. What other skills are necessary to be selected for RCCT?

5. Is there anything I should know going into the interview process? Are the past interview questions/cases posted?

Thank you guys in advance, any help is appreciated!!
