RC was one of the few sections for the DAT I did not study for. Honestly, it isn't that tricky, and I think S & D is a huge gamble. You should have time to read the passages. I got a 24 in the RC section and I had a solid 12 minutes to spare when I was done, and I read every passage. I did scan the first 4 or 5 questions before I began reading, and then just answered them as I went along. I had a lot of tone questions on my DAT which involved "completing" an appropriate sentence and judging the author's style.
10 minutes for reading a passage is fine, for you only have 3 passages with which to contend. Another 10 for answering questions is also great, since that will bring you out at exactly 60 minutes.
Post scriptum:
I can't speak for bootcamp, but I tried one RC test on achiever and got around a 17 which was not representative for me at all. I thought the achiever was absolutely dreadful, and the answers given were more than dreadful. Whoever wrote them was very pedantic and rather inconsistent in their logic for what is correct and incorrect. I read some passage about chocolate that was supposed an "objective" piece because it included "facts", when, in truth, it was one of the most biased and incoherent pieces of "science" literature I'd read in awhile...
Don't psyche yourself out on the reading, you can do it as long as you aren't a slow reader and you can remember information from 10 small paragraphs at a time.
