Whether you realize it or not it is a choice. and I'm not talking about buying time. Here my honest advice. There is no reason for you to have low time when you graduate! Work your a^^ off and get your ratings early. Then spend the rest of college life gaining hours and experience. Do whatever it takes! (ie... flying sky divers, flight instruction, aircraft deliveries, banner towing, charters, ect...) I entered college with 110 hours and a private pilots license. I graduated with over 1700 hours and over 700 multi Commercial single multi land and sea, CFII/MEI. I was in new hire class at the airline of my choice two days after my last final exam. (was also offered jobs at three other airlines) It can be done. I had no financial help from family and paid for all training and college myself. make that still paying.

Your goal should be to get hired as soon as possible not with as little experience as possible. These two things are not mutually exclusive. Don't graduate with nothing but the 250 hrs you got in training. It will greatly limit your options and in previous years would have left you with none.
