Group- School

I'm a junior at Lane Tech and I will be taking the ACT's soon. Im really not worried about it at all. All my practice test coming up suggest that i will get about a 23-25 so I'm happy. One thing that is stressing me though is choosing college. I didnt think it would be this hard. It wouldnt be as difficut if I knew what I wanted to major in, but i dont know. Im stuck between biology [premed, electrical engineering, and economics. Hopefully after I get my offical ACT score, I will probably have a better idea of where i will be headed
