How would I fix the bolded sentence to not be a run-on sentence? It says what I want it to, but I would like a better structure or choice of words.
While I studied at ABC Community College I worked a full-time job in order to support myself. Though the work was rewarding and necessary, it limited my ability to focus on my school work. Even though I was able to work with my professors to extend deadlines and make up missed work, my work responsibilities limited my ability to complete assignments and prepare for exams. When I transferred to XYZ College I learned to better manage my time and adapted my life to balance work and school. I was able to finish my undergrad with a much higher GPA, even though I continued to work full-time.
