I actually go to school with someone that had a similar experience with Kaplan verbal. He took the old MCAT after just a brief review of pre-reqs and a couple of AAMC practice tests and got a 6 on the verbal. He ended up taking the Kaplan course and "bought in" to their verbal method as he puts it and ended up scoring a 32 (10/11/11) back in jan. He said similar things about how it takes longer at first but you'll eventually get faster. He swears by it but I've been skeptical/stubborn about trying it after reading on here about how "Kaplan/passage mapping suck" lol. After hearing from someone else I may give it a try.
I'm by no means a verbal expert. But I've significantly improved by percentages in AAMC passages from 60% to 85% by watching the 4 cambridge learning center videos on youtube.
It encourages an in depth reading of the passage. You use analysis on
rhetoric (relationship of sentences) to identify:
Topic sentence of each paragraph (usually first sentence) -
Key idea of the paragraph. Every thing after will by used as support or to elaborate. Also can be the main point of the passage if this paragraph is the thesis paragraph.
Conclusion sentence - this is the
significance of every thing stated between it and that first topic sentence of the paragraph.
These are the main points you remember on your first read through. While you read the paragraph, you also look for rhetorical cues, or indicators of importance. Here are some examples:
Pivotal words - but, and, therefore, etc...
Quotation marks - author is saying, pay attention to this - and it either is support for the topic sentence, a clarification/definition, or most importantly,
irony - where the author means the opposite.
Semicolons and colons - the author uses this to indicate importance. He's saying, this is important and I'm going to say it twice in two different ways. Usually the most important thing is what comes after the semicolon/colon.
So you read the paragraphs, reflect on the key ideas (topic sentence) and significance of the paragraph (conclusion sentence) and you have mapped out the important cues of each paragraph but you don't really need to memorize them, just know where they are when you need to answer a question.
So how do you tell the meaning of these sentences? You use
grammar analysis. Grammar is the relationship of words in a sentence. You basically find the
main clause of that thesis/conclusion sentence, the NOUN VERB part of the sentence that doesn't rely on anything else to support it. You strip down the modifiers and you have the idea.
When you answer questions about the passage, you are asked to identify key ideas, reasons why author mentioned things, and inferences. This is actually pretty simple. You identify the location of the question reference within the passage and you use the thesis or conclusion sentence to associate the key idea or significance.
For inferences, you usually relate key idea and significances (PLURAL) together to draw a conclusion about why the author mentioned it. This also goes for questions the author asks in the text.
Now these things aren't always black and white, but with enough consistency and practice, it becomes second nature. This is what I've been noticing in my work with it, and as I understand this more and more, it saves me time answering questions.
