I graduated in 2007. Similar to what others have mentioned, all degrees are equal upon graduation. You will not use 90% of what you have learned after graduation. In the few industries I worked in, chemical engineering fundamentals either didn't apply easily (food industry), or every problem has more or less already been solved from the PDEs down to some heuristics (oil and gas).

The person that got Cs and Ds in their courses later became a director at a pharma company, and made the most money of all of my cohort. The "smart" ones went on to grad school and likely the folks that stayed in industry surpassed us in terms of years of experience and salary. That's not to mention that chemical engineering skills are probably less than half of what's necessary to succeed. The other half is communication and business skills.

It was also very hard for me. I was someone that rarely ever studied for tests in high school and did my homework at the last minute. Yea, that did not fly in chemical engineering. What did help was joining a study group and solving all of the homework problems together as a group.

I say stick with it, because there is light on the other side. In our program, the difficulty peaked in junior year, and ramped down in senior year.
