Use “International Baccalaureate exam(s)” on first mention; after that, “IB exam(s).”
initials in names:
Try to avoid middle initials in publications unless a person typically uses them as part of his or her name. Initials can be used as part of a signature (“UC Provost Jane M. Smith”). Note that a space is typically used between two initials in a name (“E. B. White”). One exception to this rule: Former UC Santa Cruz Chancellor M.R.C. Greenwood uses no spaces between initials.
Capitalize (the Internet is considered a “place”). Avoid using “on the Internet;” use “online.”
Do not capitalize (an intranet is one of many)
