To show your commitment to computer science, I would strongly recommend working on side projects where you can showcase your technical skills in the field. If you have a website or projects you completed due to your computer science skills, you will want to highlight this on your resume. Remember that the best resumes are those that are filled with accomplishments versus descriptions. If you finding an increase in your GPA term after term, add that as accomplishment. For example - Increased GPA 40% over 3 semesters, upon changing majors from sociology to computer science, resulting in a 3.30 Major GPA.
During the career fair, you will want to have your elevator pitch ready to help the recruiter/company feel convinced you are worth the taking the chance on. Provide a high level summary of what has helped you increase your GPA and why you made the switch. Be honest and genuine, allowing recruiters to feel your passion for your career in computer science and for their organization. Stay in contact and network with the individuals you meet from the various companies, and this will, hopefully, help you get your foot in the door. Best of Luck!
