Lawrence tech and a bad freshman year

Hello I’m currently a freshman. This year hasn’t been too hot and first semester I finished with an A, 3 B’s and 3 C’s. I’m ending the third quarter soon and I’m failing 3 classes and have a D+ and the rest are B’s. I have a small chance of getting these grades up and have a chance at bringing them up next quarter but I’m wondering if I totally screwed my chances at getting into Lawrence Tech. My dream school. I want to be a mechanical engineer for NASA or maybe a geologist or maybe a psychologist I’m not 100% sure. My GPA last semester was a 2.6 or 2.8. Did I ruin my chances??
