Do NOT take this class with this teacher if you don't have to. She is unclear and you can barely read her notes. She has awful handwriting and her voice is quiet and not understandable. There is only one homework assignment each week, but you don't know how to do any of it because she is so awful at explaining everything. I would not recommend.

Avoid this class if possible. If you're trying to get into business, there are easier courses to take that won't destroy your GPA. There's homework due every Friday. She only curves tests if the class average is under 75% (it almost never is). Worst class ever. She's a good person, but a terrible teacher.

Worst class ever

Do not take her class. She goes way too fast, Its insane. Her class and teaching sucks. Her handwriting is awful, and she teaches us things that we don't even need to be learning, wasting our time. She does give extra credit, but the class is tough. She's a horrible teacher and does not know how to explain anything.

The worst teacher I have ever had. puts things on the test that were not once gone over in any lecture or discussion

The test's count for the majority of the grade and she doesn't curve. The tests are long and there is a time constraint so you need to know how to go quickly. WORST CLASS EVER WORST PROFESSOR!! DO NOT TAKE THIS CLASS, DON'T HAVE HER.

WORST calc teacher out there. She fails a majority of her students, probably so you have to pay to take it again. She also has a voice that sounds like when you squeegee glass, but don't be fooled she's not nice. Went in to go over my test (the avg was a 56) and she told me I wasn't trying hard enough when I had studied for a week straight.

Hard grader with more difficult exams and quizzes than the examples she provided. Plenty of homework and quizzes every week. No extra credits at all. Never sign grade with ranking.

The average for every test has either been a solid F or a D which is really frustrating since there's no curve (not sure why). Lectures are pretty painful, so I taught everything to myself in this class. Never receive the appropriate preparation for each midterm and the tests always include stuff we've never seen / reviewed. Most frustrating class.

Worst professor I've had by far. Hasn't taught 220 much so all of her practice exams and quizzes are clearly those of other professors yet she makes her tests and quizzes much harder instead of making them a similar difficulty to the practice she gives students. All the averages on her tests so far have been pretty low (D's) with no curves.

Just an awful teacher! She barely explains the problem when she is doing it on the board, only repeating what she is writing and not explaining it. She makes the quizzes and exams much harder versions of the previous ones. She should not be the ONLY 220 teacher available (shouldn't be one at all), we need Bob Murphy to teach, not Lena!

She is extremely difficult and not helpful. Her lectures are not helpful. All of the test and quizzes are much more difficult than the previous years. She gives a large amount of homework that take a lot of time to complete and doesn't help you better understand the topic. 3 web assigns per week with about 25 questions and weekly quizes.

Be prepared to teach yourself everything using the textbook. Her class is extremely difficult, everything is unorganized, and there is an extreme amount of homework via webassign. Highly advise against taking her class. Also, she makes all exams much harder than last years.

Her lectures are a hot mess. They are extremely unhelpful. Calc 220 is a standard class for many majors and should not be impossible but the way her class is structured is set up for student failure. I do not reckoned taking! There is also and extreme amount of WebAssigns! Her tests are also impossible and no matter how many practice exams you do!

Guaranteed nightmare. If you take this class, you will have to learn all the material by yourself. Stopped going to class because all Lena does is scribble incoherently on the board rapid quick. My hands got cramps from trying to write so fast lol. A Jackson Pollock painting makes more sense than her lectures. Asking her for help? You're dreaming.

Terrible

1. Terrible lecturer. Spends the majority of time writing out the solutions to problems but scarcely explaining the material. You're better off just going on Khan Academy everyday to understand how to solve problems. 2. Rushes and speeds through the material while somehow barely teaching. 3. Don't get her as a TA. She just solves problems FOR you.

If you can learn by watching someone scribble nonsense on the board this is the class for you.

You know somethings wrong with the professor if the class avg is 50-60%

Horrible as a teacher, has no idea how to teach a class and has no idea about the material whatsoever. Do not take, your other option is probably Guzman, she is horrible as well, but still better than her.

Her lecture sucks. You can barely see her handwriting even if you sit at the front 5 rows in the lecture hall. She simply reads her note for almost every lecture

I'm sure she's a sweet in person, but taking calc 2 online has been awful with Lena. She doesn't post material when she says she will, leaving students to scramble when she posts homework less than 24 hours before its due, or posting worksheets after the synchronous zoom, or practice exams less than 2.5 hours before the exam. Easy A but STRESSFUL A

Fall 2020, COVID semester. SO unorganized!! Always late with posting assignments. Grades are made up mostly of exams and she won't upload answer keys until literally an hour before. Don't expect her to email back EVER. Mostly learning from Discussion (your TA) or on your own. Didn't watch lectures rlly ever, learning from outside is more useful.

zoom proctored tests. no notes and no calculator

Don't take this class. I studied for over 20 hours for the final and ended up getting a 40%. This class caused me to much stress and anxiety I can't even explain it in words. The amount of midterms is ridiculous and the instructor doesn't know how to lecture AT ALL. The TA's do most of the job.

Terrible professor. Lacks the ability to properly teach the important basics of crucial topics. shes nice and seems to love Calculus but her teaching is just not a good way to learn in this class. Her lectures are very confusing and often times are incomplete. Does not respond to emails and does not prepare you for exams.

She is a terrible professor and I had to learn most of the videos from Youtube as her lectures would not reflect Webassign or other homework. The nice thing is quiz retakes, but even then I had to put in hours of extra time in the class because she would not teach.

She is a really bad professor and she never responds to emails. Her lectures are not helpful and you never understand what is happening in the class. I had to look up YouTube videos in order to understand what was going on in the class.

Online lectures were often posted late, and videos were under 10 minutes while lacking all material we needed to know. Often our TA's would have to spend our discussion time teaching what she failed to teach. Theres a midterm every other week and she never responds to her emails. Get ready to self teach your course through youtube.

Her short lecture videos are no where near detailed enough to complete the homework. We have about 6 assignments due each week. We get 2 lecture quizzes, 2 group worksheets, and 2 homework assignments to complete each week. The class would have less complaints if her lecture videos were detailed instead of 5 minute short clips with little effort.

Lectures are 5-10 minutes long each. After 4 weeks, she decided to stop teaching and now just presents "example questions" and doesn't complete them. This week, we had two lectures. Both of them refused to explain the theorem being covered and only provided incomplete example problems and told us to read the TB. She also doesn't respond to emails!

What she does in her online lecture is just to show you endless examples. She never explains any theories and the logic behind them. She just solve a question with her knowledge and left you alone, wondering "what the hell?" She is such a terrible professor. No one should take her class!

She sucks. Horrible lectures that don't teach, and then throws you tons of homework and bi-weekly tests unlike any lecture content. She never responds to emails or campusboard posts (in a COVID semester, nonetheless), leaving you out to dry. Luckily, the TAs help, but they're doing her job bc she's lazy and refuses to properly teach. DON'T TAKE HER

Does not respond to any emails, with a fully online class it is impossible to learn. "Lectures" are a collection of sub 10 minute videos that are just straight up worse than some outside material such as khan academy. Class isn't the hardest class in existence, but she just does not try to help anyone at all.

Never answered emails and gave horrible lecture videos that did not cover everything and explained things poorly.

Calc 2 isn't a hard class, but this lady makes it more difficult because of her disorganization. Useless lectures. Practice materials get posted 4 days before the largest exam. Completely absent from Campuswire. TAs teach the class, not her.

Hard to believe she is the professor when she is never present for office hours and relies on her TA's to teach the entire class. She gives lazy lecture videos which are unhelpful and tons of work. Not to mention we have 6 exams in total. Probably the worst professor I've ever had, she just doesn't care

By far worst prof i've ever had. I had to teach myself this whole semester. Never responds to anyone's emails. Its like she disappeared or doesn't care. Basically the TA's are your only help.

Doesn't respond to ANY emails. Even my TA has trouble reaching her. Lectures are brief, incomplete, and don't cover the exam content. Our TA constantly has to fill us in on important material. Also, she sniffles and sneezes every minute or so in EVERY lecture. It's incredibly irritating. Finally, why is every lecture video in portrait mode?!

Lena is quite literally the worst math teacher i've ever had. she's so unorganized, doesn't answer emails, her pre-recorded lecture videos often include "finish this problem yourself," and doesnt enter grades for weeks on end. you're lucky if you know your final grade before its time to drop a class.

I'm someone who's gotten As in math classes all their life, this class being no exception. That being said, this has been the worst class I've ever taken. Please take the proficiency test or something. Material is constantly posted late, questions are never answered, and lectures are unclear and inadequate. Basically taught myself the entire class.

Absolutely horrible. Never responds to cries for help. Basically YouTube taught me this semester. Seems very lazy and apathetic towards students even though she says things like ask me if you have any questions. You can ask, shell just never respond. Im someone who usually does well in math and this semester has been extremely frustrating.

Why does the homework never match the lecture???? What is covered in the homework is always not covered in the lecture. And terrible handwriting.

Had her for Math231 this past semester; she's impossible to get ahold of in general and is basically a nonexistent resource for getting any kind of questions answered. Her lectures were also not very informative most of the time. Also had about 5-8 hours worth of work every week. Offered terrible support to students for such a hard class.

Lena is possibly the worst professor, or teacher in general, I've ever had. Her lectures, if they can even be called that, are short, uninformative, and often incomplete. The TAs carry this class. She also NEVER responds to emails. Biweekly exams suck. Practice exams don't reflect exams. Frequently makes mistakes in explanations and never fixes.

The online semester under Lena for Spring 2021 was horrendous. Her lectures are unclear. She doesn't explain the content very well. I relied on other online sources to learn instead. She also disappeared and ignored Campuswire forum questions. She, however, allowed retakes, which was helpful for me and allowed me to improve on my proctored exams.

I paid for a full course and I got a self learning program. The lecture are basically useless, The homework is way too much for the points it worth. Will not come again

Lena was not up to the task of being the only 231 instructor. We all had to learn basically everything on our own. Office hours were always full and she was extremely slow to answer questions. The only reason I got my grade is because they implemented an extremely generous grading structure that essentially guaranteed a C. This won't happen again.
