So I think that attending helped me realize I needed to get my act together. Before attending I had a 3.5 GPA and only volunteered 4 hours a week. I met people with perfect SAT scores and 4.0s as a freshmen at HU. I was like... oh snap, I need to start doing more. So it was helpful to see other people from different universities and how driven they were about dentistry and medicine.
The program was good. We had classes 4 days a week 8-4pm. We took biochem, genetics, physics, orgo, ethics, writing. The ethics and writing weren't terribly helpful because how much can you learn in such a short amount of time? The sciences courses were a like a trial run before actually taking the class at your own university. I did well at HU, but I did GREAT when I went back to my own institution and already knew the concepts/application of the science. At HU we didn't get to dive in all the material you would cover but we did cover enough to give me a slight advantage. We also have shadowing once a week which was fun. Got to watch a couple surgeries and go on rounds. We met med students who provided useful advice. We went on planned trips (NIH, med museum, six flags). Overall, it was the perfect balance of work and fun for 6 weeks.
