Reading Comprehension

I've done fairly well on all RC EXCEPT science related passages. Now, the goes back to my middle/high school days when I dreaded taking science courses. I always feared big and wordy textbooks on science topics. Well, that fear is back! I have a tough time getting through complicated science passages. I feel that I'm overwhelmed with the different comparisons, arguments, and most of all - understanding the message. Again, this is a reoccurring problem with SCIENCE related passages.

Does anyone have a similar problem? Have you found a way to overcome this hurdle?

Also, if you ARE successful in Science related passages... do you have any tips/hints/suggestions for me and the community?
