Hey congrats on being accepted! As far as the driving situation parking ha been fine as long as u come after5pm to get the 5$ parking deal. I have also taken the train and the area is pretty populated do I never felt unsafe... Although I will say that the colder it is the less people that are out which may make some feel uncomfortable but I would consider it safe. I come from the pa sunburns as well...the hesi is worth 5% q2 and it goes up to 10% for the rest of the quarters. So it really doesn't effect your gpa too much.
