She's a great teacher if you really want to learn math, very clear, but gives a lot of homework. I don't think I have ever had a teacher this knowledgable- she knows her stuff and teaches it super super well and clear.The homework load is insane, but if you can get through it, the tests are easy and you are very prepared. Only problem with Mrs.Korsunsky is that she is biased but pay attention in class and do your homework and she'll be fine with you.

Rita is a very good teacher. She gave too many HWs but really help students prepare AP test very well . Some exams are hard and maybe not have enough time to finish. She knew how to encourage students and balance the pressure.

Not a bad teacher; very boring class and she usually just reads off the slides, but she absolutely does know what she's doing and she'll teach you everything you need to get a 5. Overall, good in terms of knowledge, bad in terms of workload and excitement.

Also, a lot of people here might complain about the hw workload. However, this is from my experience from this year (don't automatically assume for your year tho, cuz it could be diff): it's a waste of time to do all the problems; it's not worth it. I recommend doing maybe every other problem, and then studying her worksheets inside out. Book problems typically aren't even on the test lol. However, this really REALLY determines on your TA. If you have a bad ta, then forget what I wrote

For Korsunsky's class, always do the worksheets for tests; much of it is just based off of those. Also, in terms of personality, although she may seem more strict inside class she's more chill outside of class (like she turns into a different mode lol). It's usually pretty chill as long as you study and have chill TA's (one who aren't will make your life hell). The only test you really need to worry about is the Revolution of Solids test, which is always the one many people bomb

First of all, Ms. Korsunsky's class is EXTREMELY boring, at least half the class is asleep everyday. However, she always tries to make sure that we understand the material, and her tests are always easy if you do the worksheets she gives us.

Its unfortunate when teachers start focusing more on their statistics (being able to say what percent of students get a 5 on AP test) than on students. She makes students work insanely hard and then deducts points for illogical reasons. If students ask her why points were deducted, she often doesn't give a reason. She makes them work so hard and still they don't end up with As. Its all about getting 5s in AP test and kids end up getting Bs in Math, because she makes things so hard.

It's funny because I remember people used to want Korsunsky over Dybdahl but now it seems the opposite is true. No matter which BC teacher you get, you'll come out with a ton of calculus in your head. Korsunsky demands hard work and sometimes homework will take 3 hours (sometimes more in my case) but it's not like Dybdahl doesn't assign a lot of homework either. Work hard, when you get to sequences and series you'll feel like a genius.

She clearly works hard to ensure her students understand the material with the amount of powerpoints she makes and all the practice problems she gives out. No wonder 92% of people got a 5 last year on the AP Test. She does CLEARLY pick favorites and only really likes people who make math their entire life (she will repeatedly make this clear). However, her class is an easy A for those who work hard and stay proactive.

She only likes math club people and people who do well on math Contests. She does not really care for the average students in math out there, however I learned a lot from her, and the class was a pretty easy A to get, so I'm not complaining.

The best teacher for Pre-calc/Calculus BC. You definitely want her over Dybdahl. Her tests are kinda hard ish, and she gives quite a bit of homework at times, but is an easy A. She throws extra credit points around like free candy (go over 2 homework problems in a day for 1 point).

I had her for PreCalc and her Precalc class is really easy. Sometimes she gives you study guides that are the EXACT SAME QUESTIONS as the ones on the test except with the numbers changed. I had a 99 in her class both semesters. Oh and she's a really good teacher and super funny! The trig methods she teaches you are really useful, especially for the Math SAT II. I have her for Calc this year! :D

if you're moderately smart and pay attention to her lectures or read them after and keep up with your homework, you'll get an A and a 5. only downside is she won't let you take notes on lectures so some stuff gets lost in translation.

Do your homework. She expects ALOT from her students and often makes them feel dumb. She used to be a good teacher. From my experience, she's not. She just has a ton of stupid powerpoints. If you're not a math person or taking alot of hard classes, maybe consider an easier option than bc. She's not all that nice and has big favorites (the smartest people)

Pre-Calc-easy. Calc, a lot harder. Do your homework each day and don't get behind. If you do not do homework, you will get on her bad side. I speak from experience. Use class time wisely. She does not really have that much time to answer your questions unless if you are in class. Overall she's a good person and only wants what's best for you.

mrs. korsunsky is definetely the best math on campus. she actually teaches you stuff without being too overly difficult and confusing. her personality is awesome and she never gets angry. I had her sophomore and junior year and now, I actually miss having a math class. she preps you like no other for the AP test and her class tests are pretty straightforward. take her advice whenever she gives it!

Difficulty - fairly easy class if you do your homework every day and pay attention during class - harder than you think: powerpoints on block days can induce sleep. She is helpful if you ask for help, but nothing extraordinary. Clarity - this really depends on if you get the subject material or not. She does go over the tricky stuff several times, which helps; you need a quick brain to keep up.

I had Mrs Korsunsky for pre calc and she's pretty easy. She's also extremely funny with her accent and her quotes. "Don't touch my screen guys, don't touch my screen." or "Who want to do these scary problems?" Overall, I think Mrs Korsunsky was a very good teacher because she explains everything clear and makes everything easy to understand. She also know's everything about calculus.
