I tend to read the passage as a whole first and get a good sense of it. I will then re-read the parts of the passage as necessary. However, this is not a fixed rule: some might do it very differently. I guess it comes down to what you're more comfortable with, but keep in mind that TOEFL RC is much easier than GMAT RC.

In addition, you have plenty of time for TOEFL RC. 20 mins per passage. You can definitely go by reading the passage first and then re-read parts of the passage when necessary while answering questions.

Thanks guys, I agree, that we havs about 20 mins per RC but in total we have 14 questions also.

Besides, I wanted to know the real need to read the whole passage. My understanding is for each question the specific para is identified in the question, it is only the last question in which we need to write the summary, which in any case is covered by all the previous question.

Since you guys have already taken the test you would have a good understanding.

Please advice.

Thanks,

Vineet
