Biography

My name is Joshua Hale I'm a rising senior at VCU. My major is applied mathematics with a minor in general business. I have a 3.78 GPA and am expecting to graduate May 2022. I don't have a huge tutoring history, but I've always helped my friends out with their math classes. I've always been the "math geek" in the group who everyone looks to for help, and I never had a problem with helping people because it's what I loved to do already. I love math and catch myself just doing it throughout the day seeing if I can challenge myself. So this summer I decided instead of being unhappy at work why not just get paid for what I love to do all day anyways, and this opportunity came my way.
