Hi,
I want to check should i read the passage first and then jump on to questions, or should I start directly with questions?
I think you can do either, but we generally teach reading first, questions second.
Maybe @gregmat can confirm if its different for TOEFL than GRE
At the very minimum, you want to get a main idea of each paragraph before moving on to the questions, in my opinion.
ideally how much time one should spend on skimming out of 17-18 mins on one passage? @gregmat
I struggle with timing too. I can answer all questions, but it takes me more time. If we skim the reading to get the main idea and then answer each question that will be helpful
For skimming, I read the first and the last pargraph fully, and the first and last sentence of all other pargraphs. I do not know if this is the right approach, but it does provide you with the main idea of the reading.
