SAT CR grade fluctuates?

<p>Hi fellow CCers =)
I am currently experiencing CR fluctuation. Sometimes I'll get a 760 on practice tests and other times I'll get as low as 630. However on all practices, my Sentence Completion parts remain relatively constant(usually 2 wrong/test). The paired passage sections always mess me up, but it really just depends on the content. (hate music passages)
Any advice??</p>

<p>There are always going to be some fluctuations. If you are not using the blue book that may explain it…those tests aren’t accurately scaled. </p>

<p>If you are using BB then try to identify why you get them wrong. Then just keep practicing.</p>
