The first mistake you did in your life is you chosed "BIOLOGY" as your Major. Now, I've seen many people in sajha who seem frustrated with Biology/Chemistry for future job perspective especially in the United States., unless you wanna be Doctor or Professor. I strongly suggest you to go for technical subjects like Pharmacy (that's what you're thinking about too, which is goo). If you can get into any Pharmacy School go for it, At least you can make good money in that field. If you again choose to go for MS/PHD in Biology/Chemistry, you'll work your ass off for 5 years and get nothing at the end. Maybe 45-50k/year ? or become a Professor and make 50-60k ? ?

Go for technical field or change your major now. This is the time. Act now brother. Otherwise you'll be doomed like many of us.
