Do your schools have AP mock exams? My school has it for all AP classes you take, but my Lang one is tomorrow and I do not feel prepared.
@neoking we take our mock exams in late April or early may
I feel so overwhelmed by all the different classes offered for seniors. Too many options to choose from!
I love class selection season. My school is fairly small, and my schedule is pretty straightforward, but it’s nice to be given power over my education instead of having to fight for it, for once.
In other news, I’m completely overwhelmed this February. I’ll be out of town for several weekends, and busy on the others. Third quarter is loads of work, as always, but I’m having trouble staying concentrated. I have tons of long-term projects, for school, for myself, and for the summer, that I’m neglecting. Ahh!
Has anyone watched the 5th wave? I’m reading the book currently and don’t really know how I feel about it lol…
@Cece0499 I read it a long time ago so I don’t remember much of what happened but I remember I didn’t like it that much. That’s why I never read the rest of the series.
@Cece0499 I never watched the movie, but I saw the trailer for it while going to see a different movie. It looked exactly like every single other dystopian future teen movie out there. I even won a bet with some of my friends when I said that it must be a trilogy because all YA dystopian series come in trilogies. So, I don’t exactly think highly of it, but that is based solely off the trailer
How’s the book?
@Cece0499 I never read the book series (I haven’t really read much in my spare time up until this year, when I made it a New Year’s Resolution), but I saw the trailer and I wasn’t really interested in it, particularly because the movie didn’t really seem to have a compelling plot (the storyline seemed generic, and the movie didn’t really get impressive reviews) and it seemed to lack diversity (though that’s a story for another day.)
I haven’t been on here for a while because I’ve been swamped with work lately, and when I’m busy I block this website so that I won’t be distracted. I was busy preparing for so many things - SAT, the USAD, AMC, MESA, JNHS, etc. - that I eventually decided to drop out of my USAD team this year because I was so busy, and I doubt I’m going to finish the service hours requirement for Key Club this year since I still have to do community service for NHS.
@Greninja There just aren’t enough hours in the day to do the things I want while maintaining my grades. I feel you 
@neoking Yep, prioritizing is super hard! So is time management (at least for me, haha).
Totally… I’m already super busy this year I find it so hard trying to avoid hanging out with my friends especially since I want my priorities right lol
Can someone help me with AP Calc, I’m trying to self study, but limits are confusing me a bit. Here are the problems I need help with:
lim (x–>a) (cosx - cosa)/(x-a)
lim (x–> infinity) xsin(1/x)
lim(x–>0+) lnx/(lnx -1)
Please explain each step and how you figure out what rule to use. Thanks to whoever helps!
I would try to help @YoohooAddict but I’m just a pre-calc B-earner myself.
How many of you all have jobs? Just curious.
@MissSuzyQ Same I’m taking pre-calc currently.
@YoohooAddict I’m in Calculus right now, but I’m really bad at limits, so I’m afraid I can’t help you directly. But, I copy and pasted your first question into google and this link came up:
http://mymathforum.com/calculus/29454-trigonometric-limit.html
Maybe this could provide some guidance?
@foliontai I don’t know why they trouble me. Like I finished derivatives in a day or two and didn’t have problems, but limits I did in like two to three days and I have problems with the questions and how they’re solved. Ugh
@YoohooAddict I’m in calc as well but got a C on the limits test. However, I would recommend using this website

@tigerman333 @foliontai I thought limits were the easiest part of Calc, but it turns out they’re harder than I thought.
lim (x–>a) (cosx - cosa)/(x-a)
Use L’Hopital’s Rule…take derivative of top over derivative if bottom
You get lim (x—>a) (sinx)/1. plug in a and you get (sin a)
lim (x–> infinity) xsin(1/x)
Think of the end behavior…it has a horizontal asymptote as x approaches infinity of 1 so your answer is 1
lim(x–>0+) lnx/(lnx -1)
Plug in 0.001 and 0.00001 to see what number it is as gets closer and closer to as it approaches 0 from the right hand side. It seems it approaches somewhere around 1 from the right side.
Sorry if my directions are unclear, I did it really fast so feel free to ask me more questions @YoohooAddict
@YoohooAddict the first one is the definition of a derivative, and the answer is the derivative of cos(x) because it’s basically the slope formula (y2-y1)/(x2-x1) but at a point.
And for the ln(x) one I would use L’Hopital’s rule
