Here are some tips for reading,
1) Give some time in start (1 minute) to know what the author is talking about....(focus in the first paragraphs)
2) Scan how the author builds the rest of the passages
3) Read the coclusion carefully
4) Total time for step 1-2-3 should be not more than 5 minutes
5) Think for 30 sec and make a brief idea about the passage in yr mind
6) Look the questions now::
7) If it's just asking for a meaning answer it straightly don't go back to the passage
8) Question refering to the passage : better to go back to the paragraph and locate the answer....(it's not that difficult believe me)
9) The real challenge is with the infer question or the chronological order or the table question if you can save some time : Spend on these type of question
10) Give enough time to read in varieties of materials,, like newspaper, sport news,... and other related content
11) If you really think you messed up make a wise guess (don't be blind)
12) recongnize traps and extrapolation
