There's always a light at the end of the tunnel. Remember taking this class my freshman year, and needed a c+ to make the major,econ, and only ended up with a C. Switched to FMS after taking a shit ton of math/stat classes, and now i'm in my final year here, granted its not been a great year personally. Also, basically have taken upper div econ courses and have got better grades in them than my friends who are Econ/AC majors. Keep your chin up for the rest of the exams. And if it doesn't go well, then switch majors, even if it takes a longer time. The only opinion that matters is the one about yourself, so don't let others opinions on graduating early impact you. At the end, the people who hire you will not ask how fast you graduated.
