is it my problem???

<p>CR is my worst section,and i have tried to improve it in the past.and the result is weird....
today i may do well on this section,(maybe getting 1 question wrong on the passages at most??) but two weeks after,i may get like 4 or 5 wrong on the passages.... is it my problem?do i need to practice everyday in order to prevent my score from ''falling down''??</p>

<p>some passages are just boring…
give me a science passage i get -0
give me something narrative i fall asleep and miss like 2.</p>
