British degree abbreviations
（重定向自Bachelor of Letter）
Degree abbreviations are used as an alternative way to specify an academic degree instead of spelling out the title in full, such as in reference books such as Who's Who and on business cards. Many degrees have more than one abbreviation. In the UK it is normal not to punctuate abbreviations for degrees with full stops (e.g. "BSc" rather than "B.Sc."), although this is done at some universities.
