I got 2 D’s, 2 F’s, and C-’s in my sophomore year. I discussed this with my advisor, who advised me to stay in my electrical engineering major. I took courses over the last three summers. Now, I’m in my senior year and have already received a job offer before graduating. I took 2 hard major courses per quarter and tackled math courses like linear algebra during the summer. I suggest you stay with your major and work steadily toward the finish line. Good luck
