Kaplan strategy is not accurate..
Try to get the main idea of the passage without underlining etc..
I had the exact problem as you before..Mainly because english is my second language and I moved here not long time back.
What has really started to help me out is go on translating the idea in your own language as you read. Basically , this might sound weird but try this:
Eg: The copywriter's first task is to get the readers' attention. This must usually be done immediately in the advertisement's headline or caption, since research shows that fully 80% of magazine readers scan only the advertisements headline.
So you go like this: You read the copywriters first task is to - translate this in your language and ask - copywriter ka first task kya hain? ( I am assuming its hindi). But do the translating in like a millisecond. ( remember you cant spend a lot of time).
Then you read further- " is to get the reader's attention"- do the same thing- translate. Keep doing this throughout the passage. the ideas will come together so clearly.. Do this fast.
Try this untimed first and answer the questions. You will be amazed. take my word, you will be. I struggled so much and kept asking the same question over and over again on here ( many people find me annoying for that now
) Then I decided, **** this, I ll just try this my way,...
and bingo!
Hey if this works for you, let me know- I'd be proud to atleast have helped someonee.
Good luck, and hope this helps. Just try it..
