I just finished taking my third CAT and overall I got my highest score in both sections, but when it comes to Sentence Correct I took a major step backwards. About 5 weeks ago when I took my first CAT, without any preperation I got 7 of 15 SC questions correct, with all being at 700-800 level. Three weeks ago I took my second CAT and 9 of 15 correct with 5 questions being at the 600-700 level and 10 being at the 700-800 level. Today I only got 4 of 15 correct with 3 600-700 questions and 12 700-800. Is this a normal thing?
I've put way more effort into SC questions than I have CR and RC but yet my CR and RC carried me through the CAT I took today when in the prior CATs those areas trailed SC.
