If she doesn't like you, she'll "lose" your lab work and give you grades based on how much she hates you. She always ignored myself and my lab partner when we had questions to ask. I find it hard to understand her English. Worst teacher I had at

Lots of online homework, lectures are absolutely pointless. She is so hard to understand and her explanations don't help at all. She makes people hate chemistry.

An utterly useless teacher. If you take her class then be ready to bury yourself in the textbook because it is the only way to learn anything in this class. She also requires that you pay $50 to buy the online code for the book. Probably because she's too lazy to collect/grade the damn homework. All in all, I HIGHLY recommend not taking her.

One of the worst chemistry teachers at De Anza. She skims through powerpoint slides without explaining them. She BARELY covers material, and when tests come around, they are full of questions and topics that WERE NEVER COVERED IN CLASS and/or are not mentioned in the textbook. Her class is very aggravating because she does not teach. Avoid her.

I was very busy taking other classes and still put a lot of effort in this class learning everything by myself as she didn't teach anything during the lecture. Even after all the effort, all she wants is making students suffer through meaningless memorization and wasting time. I didn't learn anything about chemistry, I memorized everything.

I've always received As in other classes for two years as I'm a passionate student. I took this class hoping that I will learn about chemistry. I worked very hard only to meet her expectations which is pure memorization and zero understanding in chemistry what so ever. You will fail the class if you are honest and care about learning. You are welco

This class literally takes knowledge out of your brain. I don't really write reviews on professors like this because I'm very busy and do not have time to think about minor things. However, this professor really enjoys playing with students situations and their grades. If she doesn't like you, she will give you bad grades. very very subjective.

Worst Chemistry Professor at De Anza! Never ever take her class!!! Never!!!

I am chemistry major, and I tell you: Don't take her class!!! Worst chemistry professor I have ever experienced!

Absolute worst professor I have experienced at DE ANZA. Usually I don't like to rip on professors, but this guy deserves it. Her lectures were confusing, and she wasn't helpful. AVOID at all costs.

I spent all my time studying for this class, and I was still teetering on not passing. She requires pre-lecture readings, but teaches methods that goes against the book. She is notorious for giving quizzes on the lecture that she just gave ten minutes prior. Avoid Lo at all costs. She's nice and funny, but lectures are bad and exams are worse.

Worst professor I have ever takn at De Anza. She is very nice in person but a terrible teacher. Her tests are super hard, and she does not curve. She thinks that just because one person got an A that she is a good teacher and that we are dumb students even if the avg test grade is a 58%. Avoid her at all costs.

She is the worse professor ever! You won't learn anything from her lecture and need to self study. Do not expect to be respected in this class. Your hardship means nothing to her! If you take her class, try to show yourself in a way that she would like you rather be a studious student who put her life to learn!

Run.. Don't look back... don't take any of her classes

WORST CHEMISTRY PROFESSOR. SHE DOES NOT CARE ABOUT YOU AND THE CLASS. YOU WIIL NOT LEARN ANYTHING! DO NOT TAKE HER AT ANY COSTS. TAKE DR. GRAY INSTEAD.

Unprofessional, no clear syllabus, doesn't respond and check her emails (2 weeks still hasn't responded). Docks off points for no reason and accuses you of copying/cheating. I've been here for 2 years and have taken other STEM classes, this was THE WORST out of everything. Lectures are pointless. Don't waste your time and money.

She accused me of cheating/copying and pointed out things that weren't wrong when I asked what I could improve to get a higher grade. Doesn't know her chemistry and doesn't know how to teach. Lectures are useless. A lot of self-studying. She has no idea how to conduct a class and lab. AVOID at all cost.

I can honestly say I didn't learn one thing from her that quarter. Lecture was useless. She uses a projector and writes on a paper, and 80% of the time, the paper isn't even shown on the screen. You just see her hand. You will get an F on everything, but she offered us 150 points of extra credit, so if you do all of it, you will get a good grade.

I've taken this class twice, failing it each time, despite doing all of the homework, labs, reports and online extra credit. This is warning from me to you, don't let your GPA suffer and avoid this professor at all costs. I was a bio major but I changed to cs after failing her course for the 2nd time.

Her teaching style is v unclear, so you never know what to expect on quizzes or tests, even if you self-teach from the textbook. For lab reports, her grading requirements also unclear & she doesn't tell us what she expects until after she deducts points for no reason. For example, I had all the correct info in a report but she still took points off

She never tells you what your grade is during the quarter. The worst teacher I have ever taken. Negative and doesn't give you any good feedback besides saying "You didn't study" You can never understand what she is saying during the lecture. Exams are way too hard. If you take her, I wish you the best of luck cause this class is a living nightmare

The tests are really hard and she can get really rude at times. Not to mention how ridiculously disorganized she is. Don't take her if you have a choice. She will own your life for those 12 weeks you have her. Total nightmare experience.

Do yourself a favor and don't take any classes with Dr. Lo. Even if you'll have to wait a quarter to take it with a different professor, do it! One of the worst teachers I've ever had. Her exams are almost impossible to pass. More than half my class dropped out. Im barely making it myself and I am usually a A/B student.

I took her Chem 1A during the first COVID-19 shut down quarter, so she was particularly unorganized. Chemistry is challenging for her to teach online, so a LOT of us were confused all quarter. She frequently changed due dates at the last minute, causing tons of stress. You may not want to take her online if you haven't already mastered chem basics.

DONT EVER TAKE BILLIE LO. YOU HAVE BEEN WARNED.

Key to success in her class? Don't listen to a word she says. Ignore her lectures, ignore basically everything she says. In other words study on your own. Her instructions are always a mess and often contradictory, so be prepared to argue with her about your grade. Everything in this class is disorganized as all hell.

She does not adhere to her students' needs. Inconsiderate and disorganized. Instructions are unclear and everything on the syllabus goes out the window because she does things "her way." In addition, this Professor makes you feel regret for asking her genuine concerns and questions because she gets defensive. Think long and hard before taking her.

As a human, shes genuine and a nice person. During lectures she will answer any questions you have. Thats about the only positive I can give. As a teacher shes one of the worst I encountered and even worse for exams. Its almost impossible to finish exams with an hr for 14 questions. I would avoid this teacher unless you are a Chem expert

Shes a terrible teacher who gives exams in an impossible time frame to finish where the average grade for the final exam was 64% and the average grade for our lab final was 52%. Its just not possible to do good in this class unless you are a chemistry god. Her lectures are confusing and she goes all over the place. For your gpa don't take her ever.

For the people who said she curves. That was not the case for the summer quarter. if you bombed the midterms and final, you could maybe pass with a C but theres no way you could get an A or anything close to an A, even a B is a reach in her class. The people who don't end up dropping the class are made up of chem gods, leave if you aren't one.

Unless you are a chemistry expert, your chances of doing good, let alone pass the class is very slim and passing the class is somewhat of a reach if you struggle with chemistry even a little bit. If your brave enough to take this class, set your expectations extremely low and set your grade expectations even lower because your gpa will take a hit.

had our exam 15 questns 1hr & techdifficulties she has during exam, some questions there were these images as part of m.c ? but they didn't appear during test Some questions she had would take more than 4 minutes to ans hope she'd consider the time & type of questions to ask otherwise I believe its unfair. I don't understand any of her lecture

grading is unclear, on my exam she thought that I copied and cheated because she said that my hand writing is neat( but since I used iPad's notability it makes writing somewhat nicer) and so after my final she had me on zoom and questioned me for over an hour; where she asked me ? from final exam what the process to solve? I thought this was unfair

The one good thing about Lo is that she curves heavilyother than that, get ready to be belittled for answering incorrectly, called out for being absent, etc., unless you're a favorite. I think that she doesn't understand how to properly teach or address students with empathyshe said that she learned most of this stuff in grade school.

EXAMS ARE PROCTORED. Exhausting course work that clearly makes no sense. Modules that are put up make no sense whatsoever. Accuses many people of cheating. Exams aren't the most challenging but work must be shown all the time. Some links that are put up by her rarely work. The time things are due change often without any warning. DON'T TAKE HER!!!!

Teacher is extremely difficult to follow and confusing in her lectures. She is very hypocritical in a sense that she calls out students for things like wasting time but does the same thing during class. There will be many times in which you would wonder if even the teacher knows what she's teaching. Insensitive, confusing, & boring DONT TAKE HER!!

Do not take this professor. I took her for credit because there were no other teachers teaching Chem 1b. Her lectures do not make any sense, her tests are confusing, hard, and misleading, and you will basically be self-teaching yourself the course so you will have to spend a lot of time studying if you want to pass her class.
