Education	Higher Biology (in some regions)
Business	Depends on the company or document

Always use the surrounding words to identify the correct meaning.

The topic of the conversation tells you which meaning is correct.

If you see HB in game chat, read the surrounding conversation before deciding what it means.

HB Meaning in Business
