Here's my perspective as a Manhattan GMAT
instructor: It is not
critical that you know all the terms as long as you know the rules themselves. A few examples:
You need to understand that a noun modifier must sit adjacent to the noun it modifies. It helps for discussion purposes if you know that something that modifies a noun is called a "noun modifier" but it's far more critical that you simply know that modifiers that start with "which, who, where, that" are noun modifiers.
You need to understand that a pronoun must clearly and unambiguously refer to a noun that is actually present in the sentence. It's helpful if you know that the noun to which the pronoun refers is called an antecedent, but that's not critical.
You need to know that you should stick with the simple verb tenses (past, perfect, future) unless you have a reason to use a more complicated tense. It's helpful if you are able to articulate the rule that you should use the "past perfect" tense if you have a later time period referred to in the same sentence (i.e. The fire had been
burning for six hours by the time the firemen arrived
.), but what's more important is just that you know when you should and shouldn't use certain tenses.
In short: Given your time constraint, I'd learn only enough of the terminology so you can a) understand the grammatical rules and b) know what rule or term to search for on discussion forums like this one!
Does that help?
