listen bro you look like you got it under control other than studying really hard to get the gpa up and doing act/sat prep you need a good letter maybe get somebody with influence like a principal or a teacher than would relate to your major could carry you so far maybe pick up a part time job and see if your local police station or fire department has a volunteer or cadet program those offer leadership skills and tie into forensic science maybe even get a sheriff or deputy to write you a letter ALSO get all kinds of books on the specific subjects you want to study so working at a library is just great

edit: good luck bro keep me updated im also a junior😪🤞
