Please help me make my decision? (Bio-E)

<p>I'm scheduled to take Biology E in October...but I haven't studied much in a while and I'm worried I won't have enough time to fully prepare for the test. Reading Barron's feels like an overload sometimes, even when I'm reading the chapters I know well. But I took a Sparknotes practice Bio-E test today and got a 640..I don't know the strength of that test in correlation to the actual one (this test told me I left too many blank even though I didn't leave ANY questions blank and it's longer than the actual test)..If I don't show up to the test, do I get a 0 or is it all canceled? I don't think I'll be ready for the test in time seeing as I have ~20 days</p>

<p>my advice would be to study from the barron’s book rigorously for the next 20 days.
I studied from it for 20 days straight and i managed a 740, when 20 days before i would have gotten low 600s. </p>

<p>Granted, i took it towards the end of the school year when i didnt have too much work for school. But i suggest that you study from the barrons during any free time. It goes over everything in so much detail that the real SAT doesnt seem so hard. </p>

<p>btw. i would say the sparknotes is pretty accurate. sometimes there are weird glitches but whatever.</p>
