5 Business Secrets They Won't Teach You in the Classroom College may have helped fill your head with reams of information but here are five lessons your professors didn't teach you.

At graduation, it's important to remember one thing: College is only the beginning.

As you walk up to accept your diploma and move your tassel from one side to the next, you will join many friends, colleagues and family members who have similarly moved up through the ranks of higher education. And while graduation calls for celebration, the realities of the real world should soon set in -- that is, the truths college never taught you.

Before launching your company, here are five secrets your professors likely didn't teach you in the classroom:

1. College is chaotic, business is methodical.
The tortoise and the hare isn't about speed, it's about focus. While regurgitating information twice a semester during finals week got your through college, it isn't going to cut it anymore. You can't cram your way through your startup. You need to slow down the frantic pace, have a more even-keeled schedule and strategy. Keeping your nose to the grindstone will help fine tune your managerial and overall business skills. Remember, becoming a successful BIZ Experiences is a marathon, not a sprint.

2. Your major is more than book knowledge.
One of the most honest insights I discovered from an English professor friend was her explanation of what the students got out of her class. She believed that, while English wasn't necessarily a circuitous major for a career, it was an opportunity to learn how to express yourself. College teaches you useful skills, but it is up to you to take it the next level.

3. Don't brush off your electives.
It may seem like college electives were arbitrary and primarily used as an excuse to take Yoga 101. But these courses actually gave you credit for learning about areas outside your core classes and discovering different parts of yourself. If you found an unusual class, philosophy or club that piqued your interest, by no means forget about it. Take what you learned into the real world and apply it to your startup.

4. Group projects are productive.
I'm sure you are accustomed to dead weight in group projects -- the people that do nothing but get the exact same grade as the hustlers. Don't fret, you can turn this experience into a positive one through hiring the right people. Hire smart and use individual strengths for a stronger group. Good leadership means being able to form teams according to both compatibility and complementary skills. Use your negative group experiences to build better and more effective teams.
