I don't encourage anyone to get into debt to go to college. I recommend ranking the programs and then also ranking by affordability. Find the balance, keeping in mind that a solid Computer Science undergraduate degree can be obtained from many institutions. If finances are a concern, consider obtaining an AA degree first and transferring into a 4 year institution. There are so many pathways you can take that would accomplish your goals without breaking the bank.
Definitely apply to scholarships like it is your full time job! I know one young lady who took a year off between high school and college and did just that. She was able to raise enough money to pay for 4 years of education via scholarships and essay contests.
Best of luck!
