Game plan

I am a Sophmore at a target Canadian b-school. Goal is to get a position at any of the bigger consulting companies or the big 4. Obviously hoping for MBB.

Anyways, I have some good experiences built up so far. A lot of extra-curricular activities, some office jobs (real estate, Big 5's PWM division..), started a clothing business with 2 friends, and had a client focused marketing gig back in the day. For the wealth management job I had, i worked on improving the business dev. process and have some solid numbers to back up my improvements.

What should be my game-plan from here on? I have the rest of my sophmore year and the summer to prepare and shape myself and my experiences for consulting. I intend to go through Case in point and a few of the other case books this summer to work on my case-solving skills, but apart from that, what else can i really do? Is it worth it to try to start networking with individuals at MBB and other consulting firms? What should I be looking at for summer internships: boutiques, f500, big4, or what else?

Thanks in advance
