[URGENT] How to speed up for the Subject Tests ? And Practice tests

<p>Hey guys,
I am taking the SAT Subject Test on 8 November (I know only 2 days to go!)
I studied from Barron's for Maths 2 and Princeton Review for Physics. I have done the Maths 2 Practice tests from barrons and I can only reach to abut 40 or so in the 1 hour that :/
This is even worse with Physics, I can only reach up to 60 in the Princeton review test. I still have 3 math tests in barron left and 1 for physics in princeton review. Can anyone give some quick final moment tip to speed up ? </p>

<p>Also if anyone of you have links to free practice test of Physics and Maths 2 that'd be really great help. I looked on sparknotes it says practice tests are your best friend but I didn't see any. Also if you have any other sources for test It'll be of much help
Thanks. </p>
