Need some help before December 1st SAT

<p>Hey guys.</p>

<p>I had 3 months to study and I didn't do much, but this last month I've really put in a solid effort and was focused. I took one test a day (BB, Online past papers) and carefully analysed my errors</p>

<p>I started the BB and as I went through the tests, and my score ranges moved from the 1800-1900 to the 2100s and low 2200s.</p>

<p>I was really happy so this weekend I kind of slacked off. </p>

<p>Today I took another test just to get back into focus and my score went way down to 1890-2090.</p>

<p>Is it because of the two days I slacked off, or are the tests getting harder as I move further in the book?</p>
