Can you correct my composition writing, please

Some people say students should just study hard,and also when they study in college.However,I think no matter they actually need money or not that a college student should get some part-time jobs experiences. Because college students are not teenagers any more they need to prepare some abilities for the future when one day they must depend on themselves. For example, when a student graduate from the colleges, and go to find a job that the boss will hope he has some experiences. If he doesn’t have that he may lose some chance. Also, getting part-time jobs can know other people that may help you broaden your horizons. Furthermore, it can help you make extra pocket money. In conclusion, I think college students should get some part-time jobs.
