<p>Yeah, it’s 12. I was paranoid on that question u initially, but since I had extra time I actually drew out the possible pathways for the dog (crazy, I know), and confirmed 12 was to be the answer.</p>
<p>I drew it out too. Could you explain?</p>
<p>You have to use permutation. There are two options for the first door, three for the second door, two coming back through the seond doors, and one coming bac through the first doors. 2x3x2x1=12</p>
<p>Omigosh. I did NOT realize that the dog was going back too.

That was me slamming my head against the keyboard…</p>
<p>The only reason why I got the dog question was correct was because I was quickly reviewing Grammatix the night before and it explained the use of permutation on a problem extremely similar to that one. Rather lucky, I’d say! haha</p>
<p>I could’ve used permutations, but I didn’t. I just traced out the number of paths possible for one starting door, then multiplied that number by two. If it had been a larger number of doors, though, I probably would’ve used permutations.</p>
<p>^That’s what I did too
How is the Saturday PSAT guys?</p>
<p>I can’t believe I didn’t see that he goes back also! UGH</p>
<p>This is probably a stupid question but what is a permutation?</p>
<p>[Let</a> me google that for you](<a href=“LMGTFY - Let Me Google That For You”>LMGTFY - Let Me Google That For You)</p>
<p>Ohmygosh permutations are a life saver.
… I had no idea what they were in 10th grade though so I spent like 10 minutes on a problem that needed knowledge of permutations. I got the wrong answer LOL.</p>
<p>Apparently 97 is the greatest prime number under a 100 not 89 :(</p>
<p>Pretty sure I met the cut-off for my state on the PSAT, which isn’t pretty high considering I’m in Florida. I also just finished my first quarter, now for the other three.</p>
<p>220 for California.</p>
<p>I already planned my senior year schedule.</p>
<p>AP English Literature
AP Spanish Literature
AP US Government & AP Macroeconomics (both semester courses)
AP Physics C (Mechanics)
AP Calculus BC
AP Art History
Advanced Music Honors
Marching Band PE</p>
<p>What’s your opinion on this schedule?</p>
<p>A lot of APs! Do well or else they’ll hurt you more than they help.</p>
<p>Taking the PSAT in 40 minutes!</p>
<p>@ryidol I’ve planned my senior year schedule too lol. I have two planned out because if I get this cancer research internship, I can only take 2 classes a day during senior year.</p>
<p>W/out Internship:
- AP Physics C
- AP Environmental Science
- AP Literature
- AP Calculus 1A/1B
- Latin II
- Latin III</p>
<p>W/ Internship:
1st Semester:
- AP Calculus 1A
- Latin II
2nd Semester: - AP Calculus 1B
- AP Lit</p>
<p>As you can see, I have a lot more going on without the internship, and with the internship…not so much. I still have to take my two required language requirements so I have less freedom. I really hate language courses because I’m so bad at them, stopping at Latin II is perfectly fine with me lol.</p>
<p>haha i got my senior year planned out too.
This year I’m taking like half the aps at my school.</p>
<p>So next year I’ll probably only have 4 classes, 6 at the most:
AP Chem
AP English Literature
AP Macro/micro economics
AP 2d art studio</p>
<p>Optional:
AP Environmental Science
Math at community college (taking Calc this year)</p>
<p>I’ve also planned out my senior year.</p>
<p>AP Chemistry
AP Calculus BC
AP English Literature & Composition
AP Macroeconomics/AP Microeconomics
AP U.S. Government & Politics/Sociology
Spanish III Honors
Driver’s Ed/Speech and Debate</p>
<p>Film Composition and Lit/ Science Fiction
World Religions/Economics
US Gov and Politics AP
Some sort of art, damn my school’s requirements/ Neurobiology
AP Calculus BC
AP Statistics or AP Chem or AP Envir Science(if I get lazy)
AP Physics C</p>
<p>The slashes mean semester courses</p>
