How much harder is anatomy I and II and physics I/II compared to accounting, finance and managemen?

I graduated with degrees in Accounting and Management. My overall GPA is a 3.2, but since I got some Cs in accounting classes, I don’t think that I can get into their M.S program and get CPA certificated. I applied anyways though. One of the reason why I never got better grades in my accounting classes is because I never tried hard enough. I ended up with some 79s and 89s and found the material boring. Once I forgot to do the extra credit which dropped my letter grade.

Since I have no work or internship experience, I work as a part time teller at a bank even though I have 2 supposedly useful degrees.

I have always had a genuine interest in science but was afraid to take any science classes since they may be too difficult. I don’t even mind studying for hours a day since I am interested in the subject. Since I work part-time I was thinking of going into occupational therapy,nutrition or even physical therapy. I could work and take classes. My dad is a doctor and also has lots of connections in his hospital. Only issue is that I am afraid I will fail the classes and waste my parents money.

If someone can’t easily get straight As in their finance and accounting classes would anatomy I and II and physics I/II be too difficult? Anyone with this type of experience?

I should point out that I did some pre cal./cal. 1 and college statistics but nothing too tough.

Those are two completely different fields so doing well in one is not correlated with doing well in the other. Except if you don’t try hard enough in either you will not do well.

I can only speak to anatomy, which my daughter is taking as a nursing student. It is a weed-out class for several healthcare-related majors at her university.

It easily takes 90 percent of her academic time, and she probably spends several hours on it a day between actual studying, lab preparation and other classwork. If an exam is coming up, she might spend many more hours studying. It’s not that she doesn’t get it, but there is just so much content to absorb and she is determined to do very well.

So anatomy takes a lot of time and effort.

Thanks for the input guys.
