Totally agree, don't feel like you are obligated to go with a certain companys method. Found myself struggling a lot using the Kaplan method, but I found that reading questions in increments of 2-3 while simultaneously reading the passage helped a lot for me. Luckily, most of the questions come in the order that they present in the passage expect for the large main idea questions. Also, in comparison to Kaplan I found the actual test articles a lot less scientifically daunting than the real thing, so don't freak when you are being forced to digest these huge scientific articles in limited time. Training yourself to read quickly is needed as well.
