According to AP Style, you should avoid using abbreviations for bachelor’s degree. You have to keep a few points to write down degrees.
What AP Style Suggests?
If you are writing ‘bachelor’s degree’ or ‘bachelor’s’, then you don’t have to capitalize these terms. Both terms are acceptable with lowercase letters.
• She worked hard for 8 years and got two bachelor’s degrees.
However, if you will write ‘bachelor degrees’, then it will be taken as a wrong phrase. For example,
• She worked hard for 8 years and got two bachelor degrees. (Wrong)
One more point to remember:
You don’t need to add apostrophes in Bachelor of Arts and Bachelor of Science. However, you should capitalize these terms. For example,
• She has a Bachelor of Arts degree. (Correct)
• She has a Bachelor’s of Arts degree. (Wrong)
