He was driving with a friend and got hit by a drunk driver. Mawi thought about giving up but realized he had to do this for his older brother, he knew if he did it and turned everything around his older brother would be very proud of him. He then got amazing grades read every book over that they had read in english class before a test. He just turned his life around and he got into Harvard with a full tuition. Everyone was very proud of him especially his family and teachers.
I think the significance of the story Of Beetles and Angels was even though your life could be crap you can still do anything if you put your mind to it, Mawi didn't enjoy school until he started getting good grades and getting along with the teachers. I think towards the end of the story he was very proud of himself and everything he had accomplished, which who wouldnt? Takes a lot to accomplish that much, but like I said if you put your mind to it you can do almost anything you want
