Find a technique you are comfortable with. That truly makes all the difference. I took my first RC on Bootcamp and got a 20 using S&D. I later used BYU4U's RC technique which I kind of tweaked for myself and I've been scoring 24+ on Bootcamp. I first take a look through the passage to see how many paragraphs it is. I generally give the first two paragraphs (and title) a good read so I have an idea where the author is going to take the passage. I then pick up the pace up until the halfway point. Normally, all paragraphs are roughly the same in length, but make sure you balance out the half-way point if they are not.
If the essay is filled with detailed info, after I would finish each paragraph I would quickly skim back and make sure I remember what each paragraph was generally about. Pretty much a mental map of the paragraph, if need be. If I find myself not having a hard time remembering details then I just read until the half-way point. You'll know if you have to do that or not. I then go through all the problems answering them one at a time. If you read a problem and you have never seen any of the words then it is definitely in your second-half read and skip it. Once you get through all the questions for the first half you should have roughly 10+ minutes for the second half quick read and answering the remaining questions. Save the tone/what does the author think about this statement questions for the end. If you are under 10 minutes then you'll have to pick up the pace or S&D, but if you practice this enough you should easily get through the first half and associated questions in 10 mins. Best of luck!
