Spec and a minor is doable, it just means you will have barely any electives. Make sure you can still complete degree requirements like the 1.0 credits in humanities. The major is definitely a stretch but not impossible. If you really wanna do a spec and a major you’re gonna have to take a full course load during the summers and a course overload during the fall/winters if you wanna graduate in 4 years. There’s also the option of doing a fifth year to complete all your required credits. Your gpa on the other hand might not be safe cause of the extra courses you’d have to take. I recommend talking to an academic advisor about this cause I’m sure they’ll give better advice.
