something you can do:

1.Work harder in junior year to boost the GPA. The GPA in senior year will not help which school you can get in;
2.Study hard to get a high MCAT score;
3.Go to graduate school for one year master program, make sure to have a high GPA this time;
4.Or get a job to work one or two year. The job should be research related.
5.In all above cases, a lot of EC are necessary.

By the way, money should not be a decision factor in selecting the medical schools.
