<prompt> Human: Hi,I apologize if this is the inappropriate subreddit for this. I am a medical student and Im soon going to apply to multiple residency programs. This process involves traveling often via flights, paying application fees, staying in hotels, buying new dress clothes, etc. That is, it is a pretty expensive process, often in excess of 10,000. I currently have a credit card with Fifth Third that does not give me any cash back rewards.I figured it would make sense with the upcoming expenses to get a card that gave me cash backmiles so that I could at least get a little something out of this very expensive process.Does anyone have any suggestions for a good bankcredit card that would achieve this goal? I have been eyeing PNC because it has a 1.75 cash back system but I dont really know where to start.Thanks.  <response>: The folks over at rchurning are rock stars when it comes to credit card rewards, and Im sure theyll be able to lay out tons of options for you. Good luck!
