Can I raise my practice test scores significantly?

<p>These are from BB practice tests.
I'm currently a sophomore</p>

<p>Critical Reading: 560-610 Usually 580 've been doing 10 index cards of vocab since the begining of sophomore year. Can I raise this to 750 by October or January of my Junior year/</p>

<p>Math: 680-720 Usually a 690. I've just done practice questions unconsistently lol. Can I raise this to an 800 by January or October?</p>

<p>Writing: 590-640. Varies a lot for some reason. I've also only done practice questions for unconsistently for the writing section lol. Can I raise this to a 780 by January or October?</p>

<p>Any opinions? Thx in advance.</p>

<p>Lol,in theory it is completely possible to raise your scores,but why do you ask us …
We dont know you,we dont know your knowledge ,your reasoning skills …
8 months are long time,you can improve a lot .
For example.I got 620 on JAN writing ,and now score 740-760 on practice tests
I got 610 on M ,and now i constanly get scores in the range 740-800
Still havent done any CR sections,but I believe I can improve my 600 to like 700</p>
