Just an FYI unextraordinary is a term that means ordinary and although it may qualify as a word it isn't a word any business person would use. If she is a good student she may call herself extraordinary and if she weren't she would call herself "just a regular student" other wise she would call herself a bad student. Unextraordinary is a word (ordinary) with a prefix (extra) and the prefix (un) which would mean (un) opposite of (extra) beyond (ordinary) normal or "I'm the opposite of beyond normal" which is a total oxymoron (look it up it's not an insult).
