Entering the US with multiple visas

Hi. I'm kinda confused with how this works. I currently have a tourist visa and I am applying for a student visa since I want to take my masters in the states. Once approved of my student visa, I know that they will only allow you to enter 30 days prior the official start of your school year. Can i use my tourist visa to enter the US even before that 30 days prior the start of your school year?
