<prompt> Human: Specifically, I am curious about certain things such as credit cards, working on vs off-campus, investing early in stocks, and raising my credit score early on. In addition, what are some things that could potentially cost a lot in college that I can save on if done in a thrifty manner?Would it also be a good goal to save a lump sum of money to have for use after college so I do not start off broke?  <response>: Try to cook. Its not only healthy but a lot more cost efficient. I had a meal plan first year but cooked a lot, I was able to keep fit through the year and save a lot of money. Second I see a lot of people saying study something that pays well. In my chemistry class on the first day of class my professor asked how many students wanted to be a doctor, 90 percent of the class put up their hands, he said well I suggest 95 percent of you that put up your hands start looking at other careers. What Im trying to get at is look at job market trends, see whats in demand and what isnt. This is something so often overlooked but so very important. Good luck!
