If you are an educated person, you will come up with many places in which you have to write about your qualification. According to AP Style, you cannot use an abbreviation for your degree in a phrase. There is a specific rule for the use of an abbreviation for your degree.
> The abbreviations like Ph.D., B.S., LL.D.,M.S., etc., cannot be used just after a last name. The correct way to use these abbreviations is that you can use them after a full name by setting off commas. For example,
“Bravo John, M.S., will come to show us his presentation.”
Use of an Apostrophe
If you are generally referring degrees, you should use lowercase and an apostrophe. For instance, bachelor’s degree or master’s degree.
However, if you are mentioning a subject with the degree, then, you should capitalize it without using an apostrophe. For instance, Bachelor of Arts or Master of Arts.
• I am in my final semester of Bachelor of Arts in Literature.
• I have to complete my bachelor’s degree in Computer Science.
Note: There is an associate degree as well. For referring an associate degree, you should not use an apostrophe. For instance, I have to complete my associate degree.
