As the post states, the two leading American English reference books have different rules for capitalization. Therefore, you need to pick a resource to follow and remain consistent. The rules in the area of capitalization of academic degrees of both style manuals are described in this post. Each complete sentence does need an ending period.

Taylor Dobson obtained an Associate of Science degree in criminal justice from Boise State University in 2015

I have graduated with a bachelor’s degree in English literature.

As the post indicates, if you are following Associated Press Stylebook guidelines, write “I hold a Bachelor of Science in education and a master’s degree in educational leadership.” If you are following Chicago Manual of Style rules, write “I hold a bachelor of science in education and a master’s degree in educational leadership.”

The style manuals have different opinions about how to write “associate(‘s) degree.” AP Stylebook says, “associate degree (no possessive)”; Chicago Manual of Style considers “associate degree” and “associate’s degree” acceptable. Neither guide recommends capitalizing the degree when referred to generically. Academic subjects are lowercased.

Jenny grew up in Detroit and obtained an associate degree in criminal justice. (accepted by both style guides) OR
Jenny grew up in Detroit and obtained an associate’s degree in criminal justice. (accepted by Chicago Manual of Style)

1. Jenny grew up in Detroit and obtained an Associate’s Degree in Criminal Justice.

2. Jenny grew up in Detroit and obtained an associate’s degree in Criminal Justice.

3. Jenny grew up in Detroit and obtained an Associate Degree in Criminal Justice.

4. Jenny grew up in Detroit and obtained an associate degree in Criminal Justice.

We see no reason to capitalize general practitioner in your sentence; however, we would capitalize the entire proper name Royal College.
Please see our posts When to Capitalize People’s Titles and Capitalization of Job Titles for more information.

I wonder about professional or learned titles such as Member of the Institution of Engineering and Technology or Fellow of the Royal Society. I would think they should be always capitalised but what about the following?

“Jane’s general practitioner told her that he was preparing for his exam for the Royal college. ”

How many errors did I make in the above sentence?
