A summary of my reading method
1) Read the passage slowly until you figure out the point
Usually the point will be stated somewhere close to the end of the introduction or at the beginning of the second paragraph (first body paragraph). Once you figure out the point, focus on the first and last sentence of each body paragraph, then read the conclusion carefully. Underline the last sentence. For short passages (GRE), focus on the first and last sentences of the passage.
2) If something confuses you, skip it and focus on what you do understand
When a lot of people encounter a confusing section of a passage, they stop and read it repeatedly, often without obtaining a clearer understanding and wasting huge amounts of time in the process. You should avoid falling into a this type of rereading loop at all costs. If you don’t understanding something fully the first time you read, force yourself to keep moving and focus on the parts that are clearer. What confuses you might not be important anyway.
3) When you finish the passage, write the tone and the point
Try to limit the point to 4-6 words, symbols, etc. OR, if you see the point directly stated in the passage, underline it and draw a big arrow/star, etc. so you remember to keep referring back to it. For the tone, you can write an adjective (e.g. skeptical) or just positive (+) or negative (-).
