Your initial post asked for advice on your schedule. Everyone said it was too hard, and now you're suggesting making it even more difficult? Why ask for advice when you're not going to listen to it? As much as you seem to think you're the exception rather than the rule, listen to the advice of those who have been through the process. A lot of undergrads are obsessed with graduating as soon as they can. Spread things out more, take on an internship, study abroad, etc., because with that schedule you will have very little time for things outside of the classroom that make you a better applicant, you will have very little time to enjoy life outside of school, and you may very well destroy your chances of getting into med school by ruining your GPA.
It doesn't matter if you're a poly sci major or have a double degree in EE/ChE, at the end of the day if your GPA is a 3.0 you'll be fighting an uphill battle just to get into med school, let alone getting into a med school you'd want to attend.
As for the AP bio credit, I would retake bio because a lot of schools don't look favorably on AP credit and the quality of an AP biology class varies widely. Also if nothing else it should be a free A for you.
I agree with RSAgator. Almost all the engineers I know (I am an EE myself), took more than 4 years to finish their degree if they went pre-med except for the bioengineers at our school where there's a strong overlap of pre-med courses. Also, texas schools don't need a year of english? Undergraduate is an experience you won't have again in your life n personally I think it's hard to build ur credential for medical school apps in 4 years given the strenuous EE curriculum. I could've finished in 4.5 years but i just took the full 5, it allows you to do more extracurricular activities (research, volunteering, leadership, sports, hobbies, etc). I don't know what kind of activities you have now, but if u were to finish in 4 you would be applying your 3rd year summer which means u have 2.5 years to build ur credentials, given the load of the courses (2 labs is crazy in 1 semester bc labs take forever n the reports r long n it's onli 1 unit or 2 unit sometime when the wrkload is 10+ hours a week) it is hard to maintain a balance. Research requires usually at least 6 hours, leadership requires at least 3 - 4 hours if u want a deep involvement, volunteer at least 4 hours, i dont really know how you will be able to fit that in with the classes you are taking. I am sure you would like to do other things too such as your hobbies and hanging with friends. And the hours I give are on average the minimum, i have friends research 20 hours a week bc u need to do that to actually get some decent work done. Some people volunteer at 2 places, that's 8 hours a week. You need to eat/sleep/get to places, you do the math and the schedule is pretty tight.
Number isn't everything, but it matters and there's no excuse that you were an engr major that you had a lower GPA otherwise. I personally think the engr degree is awesome n open doors to pretty much wutever u wannna do, but i think 4 years is too much of a rush. Also, why EE? do you wanna do bioinformatics? medical devices? you seem very eager to do EE? I personally am a big fan of integrated circuits. How do you like physics with E&M, circuits, etc cuz if you dont like it u'll not like EE and EE is pretty much about everything you cannot see unlike MechE, etc.
how r u doing in your 1st semester right now? also, i would recommend taking biology classes since i think it shows u can handle college level biology as oppose to AP biology which may be a big difference. Just think of AP calc AB/BC, they are jokes compared to engr math bc u dont even really need to know the theory, just u need to compute.
I think it's do-able, but why rush it n if you make a mistake along the way you r to blame for. If you don't have enough EC compared to others it will show. an extra year is nothing in the span of your life and might even get u into a better school. Good luck and you can PM me if you have any questions.
