I'll just echo some of the things David has said. Purdue FIRST Programs is a very unique way to stay involved with FIRST in college and actually get class credit for doing it. I also helped out with the Boilermaker Regional instead of mentoring my first year. During my sophomore year I helped out 1646 some and this year I am the team director. As my years have gone on, my involvement has increased because I wanted it to. Your level of involvement is just dependent upon what you want to do - it's entirely up to you. Though as David said, if you plan to commit to something, you will be expected to follow through with it.
And we're always looking for more help with the three Purdue FIRST teams. Check out
