<p>Barron's has me paranoid...I just got a 690...gah i want an 800.</p>
<p>And will i need to know these topics?
1.s=rtheta for arc length/radius or w.e?
2.Distance between a point and a equation of a line?
3. How to tell the inverse of function graphs?(how do i do this)?
4. Solve for an area enclosed by a graph?
5. How in depth for polars?
6. concentric cirlces?!
7. volume by rotation?
8. major axis of ellipses/ other conic section questions
and what should i be getting for a safe 800 on the actual exam? and are there any topics that barron's fails to cover?</p>
<p>I think you can get a 780 with a 690 in Barrons…
- Prolly
- Prolly
- You can use the horizontal line test to determine if it’s a function, but you can’t write it out unless you have the equation…
- Prolly/maybe?
- Prolly whatever Barrons tells you.
- I have no idea what you mean by this
- ???
- Most probably yes. </p>
<p>For all your other general formula questions, I would say better be safe than sorry. For strategy questions, the same, but remember, Barrons is 100x tougher. Buy the College Board blue book if you want an actual score.</p>
<p>690 on Barron’s is very likely going to get you an 800.</p>
<p>1.s=rtheta for arc length/radius or w.e?
Good formula to know, usually quicker than taking a ratio w/ the circumference. </p>
<p>2.Distance between a point and a equation of a line?
Doubt it.</p>

<li><p>How to tell the inverse of function graphs?(how do i do this)?
Reflect over y=x. If you have trouble visualizing that, just try writing a couple coordinates, flip the x&y values, and regraph them.</p></li>
<li><p>Solve for an area enclosed by a graph?
No. (100000% No if you are thinking of needing calculus to find them)</p></li>
<li><p>How in depth for polars?
I haven’t seen any polar questions before. I’d imagine you better know how to convert between Cartesian and polar coordinates and maybe how to tell what shapes some polar coordinates are. (ex: r = 4sin(theta) is a circle)</p></li>
<li><p>concentric cirlces?!
Probably not.</p></li>
<li><p>volume by rotation?
Probably not.</p></li>
<li><p>major axis of ellipses/ other conic section questions
Probably not. [Besides the stuff I already told you about conics 
]</p></li>

<p>Just be ready to work quickly. In May, I finished the first 25 questions in 20 minutes, so I thought I should slow down a bit to make sure I didn’t get tricked by the harder ones at the end. Awful idea. Got to #50 with 6 minutes left and had to go back to 7 questions. It was a very stressful 6 minutes! (I did finish, but barely, and failed to get a 800 - 780) Remember you can miss quite a few and get an 800!</p>
<p>Yeah i’m having a lot of trouble finishing for barrons… and i mean alot i have like 6 questions left after time has passed…</p>
<p>anyone else have some input?</p>
<p>bump10char. anyone else have experience?</p>
