Thread for SAT subject test : Physics in October!! Couldn’t find one… so here it is.
Just finishing up Princeton Review (Ch16). Took honors physics last year and I’ve been brushing up on topics for the last few weeks… going for 750+. Going to take the official practice test tonight and go over in detail tomorrow.
Y’all feel ready? 
Is Barron prep book reliable???
Update: Just finished grading my official SAT physics subject test (from the blue book) – got an 800! Barely though (Raw score: 60, 59 is the cutoff). Phew!
Can anyone tell me how to do #39,51, and 52 on the official test given by collegeboard?
Why is this thread so unactive?
@Achanya I heard Barron’s didn’t cover enough topics which were on the test. Most people asked me to go for PR.
I’m trying for a 750+ too!! I’m getting 720-750s on Barron’s… >.< feeling reallly nervous though!
Can u please tell me the topics barron didnt cover so i will brush through it with youtube videos… And i got 800 on all the practice test,and am so nervous because i read on cc that barron practice test is not similar to the real thing…
@Achanya You’re being sort of ridiculous, in my opinion… If you are getting straight 800s on Barron’s, a test prep company that is notorious for making practice tests much harder than the real thing, then you should be more than fine. Calm down and do something fun this afternoon, you’ve earned it!
@JuicyMango I don’t have my book with me (in school right now) but when I get home I’ll look at em. Best of luck!
Am I the only one who found PRs practice tests harder than Barron’s?
@seyll00 PR’s comprehension questions could get pretty difficult. I didn’t take any practice tests (no time) but when I took the official practice test last night I was surprised at how easy the questions were in comparison to PR Comprehension questions.
@gmanhax thanks! Whew… fingers crossed though! Hope the comprehension is easy.
Do we have to know what muons and neutrinos are?
16hours to go…
Do well guys!!! Kill it!!! ;D
It seems as if u did well on the sat physics … Can u pls tell us ur secret
@seyll00 I think they just put those there to throw us off.
I seemed to struggle the most with waves; EVERY wave can experience diffraction, refraction, interference, and follows Huygen’s Principle. That cost me like 3 questions on the practice test… lol.
@JuicyMango for #39, use the right hand rule. Thumb in direction of 5m current, fingers into page. Palm is the direction of the force. use f=ILBsin(theta), where theta = 90. therefore answer is (A). For #51, since g = 9.8 m/s^2 for all things on earth, the platform already travels at that acceleration (force of gravity). Therefore, if the platform is accelerating at 9.8 m/s^2 downward, (Fg) you dont need any force. (D). for #52, use F = m(a + g). Current weight is mg, where g = 9.8 m/s^2. to double that, you would need another 9.8 m/s^2 upward, adding to the force on the scale. (A).
