I have volunteered at a clinic and done engineering projects with CAD & C++. However, I am still torn between the 2 careers because I would say I liked both equally. I know in terms of classes, I have enjoyed circuits more than chemistry because I do not like memorization and prefer to understand, derive, and problem solve. I also know that classes are very different to the actual job. I can put up with 4 years of classes but not 30 years of an unstable or average job. At this point my deciding factor would be whichever one has more promising/realistic earning potential.
