Awesome professor! Absolutly LOVED her class. Attendence isn't mandatory for lecture but strongly encouraged. Lab attendence is required though. Labs are field trips though sometimes. Fun and interesting class. Highly recommend!

Mary O'Sullivan in my mind should receive some type of reward. She teaches the class in a professional manner, yet has a down to earth approach.You will be challenged but you will learn. Study all hand outs and study guides, and you will learn plenty. You will also get a good grade.

Environmental Biology is a GREAT class. I refer to it everyday in some way or another...Do not buy the book. Attend class. Study. Take a few tests. Enjoy the experience really... she's a great speaker, and it's all very relevant to today.

Very hard class but teaches great! Almost all tests were curved because the class was so hard

Loved this class. Lecture 2 days a week, not mandatory, although they really help. Print off her powerpoints, they are all the material for the tests. Labs on Fridays, mandatory, easy full credit. Articles and tests for every unit, and homework occasionally. Some extra credit offered.

One of the hardest classes I've ever taken, but by far my favorite. She is great. I only wish I had taken regular bio instead because it is required for many majors over environmental bio. However, since it was my favorite it was worth it anyways. If you're into environmental issues, take it. You'll love it. Just study hard. You wont use the book.

Not an easy instructor but you will learn more from her in one semester than from most other instructors in two semesters. She expects you to put in the work and is very clear about her expectations. Her teaching style is very direct, and if you actually do the work, not only will you learn, you will do well! Love her!

Phenomenal professor! She genuinely enjoys the material, and it shows in her lectures. It's not an easy course, but she's unbelievably helpful with her students. If you have to take this course, take it with her and no one else. As someone else mentioned, this woman deserves an award!!

This class was difficult, but Mary made it really worth it. She was both funny and smart and she was also willing to help you through problems. She was really worth taking if you had issues with Bio before. Just be ready for the tests.

She is a very straightforward teacher and outlines her expectations and expects you to follow them. Class is a lot of work, but if you pay attention and attend class regularly, you should be fine.

Great teacher she is passionate and makes you care about the environment. she does deserve an award. Not a lot of homework but you have to study the material and be prepare for the tests.

I'd love to take this class again. Very interesting subject and she's a great teacher. You definitely have to study a lot, but it's worth it because you get a lot out of this class. Not easy, but good quality class.

By far, this was my favorite class. The tests and quizzes are extremely difficult and require a lot of studying. All of the lectures were interesting, so even though they are optional, I recommend going. I looked forward to going to class every day. The professor was passionate about the environment and it showed in her lectures.

Class was hard, but worth it. Ms. Osullivan is my favorite teacher at ECC. She has not only helped me pass biology, but she has continued to help me through my other science classes at ECC and helped me create a better schedule than any of the counselors could. Get on her good side and it will PAY OFF.

Ms. O'Sullivan is a fantastic teacher! She is very informed and knows what she is talking about, but she will not just give you a free ride. She makes you work for your grade, but she is willing to help if needed. I wouldn't recommend getting the book, all of her material comes from PP. Take her if you want to challenge yourself to do better.

Would not recommend. Her test never reflect her material and she is informative but very hard

Shes great, and in my opinion, her material is reflected in her tests. You just needd to go over the material constantly, to avoid being behind as the units progress. She gives review sheets that are a big help. But i do recommend outside sources to fully understand her material. for clarity of course

She is a great teacher. All her notes are from powerpoints. She does not use the book. All of her tests are from her powerpoints. She is very clear in her note taking and on what you shouls expect on the tests. If you leave her class without knowing something, then that is your own fault. Take her class!

Dr. O'Sullivan is an excellent professor. She really puts forth time and effort into her lectures and labs. She is very knowledgable in this subject and is always there when needed. This is a difficult class, if you want to succeed in this class, put forth the effort. If you want an A, do A work, don't expect her to just hand you an A.

Dr. O'Sullivan is a great Biology professor. She is extremely helpful all you need to do is ask and show up to class everyday. This is not an easy class by any means but if you listen to her, study hard, you can do exactly what I did and walk away with an A.

Dr. O'Sullivan is a great professor. She is very helpful, knows her stuff, but the subject itself is extremely difficult. If you pay attention in class and study , like you're supposed to, you will be fine. I would highly recommend her.

mrs.sullivan is a great teacher! if she taught more biology classes I would definetly take her. she's very organized with her powerpoints, notes,and studyguides. you don't use the book at all so don't bother buying it, just buy the code for the online material. I would recommended her to anyone! shes the best

Very helpful. wants you to ask questions. great bio teacher if you are going into bio/med field. if i actually did work i would have done better

She is an amazing, helpful teacher. Uses powerpoints. Only lab days have mandatory attendance( you can miss 2). Bio is a difficult subject but she made it easy. Great with one on one help and always will answer any questions. She is very thorough and will prepare you well for later Bio/Medical classes. I would recommend her!

Really great teacher and extremely knowledgeable in everything she talks about. She comes off as mean but you'll get used it. She's willing to help so long as you come to class and show that you really are trying to understand the material. DON'T SKIP CLASS. You'll be buried. One or two is okay. Tests are not too hard. Never got lower than a C.

Sullivan is a great teacher! She knows exactly what she is talking about and teaches very well. She gives great examples and helps you understand. Test are tough, but if you study you will at least get a B. She uses power points for almost everything which have exactly what you need to study for the tests. Highly recommend her.

Dr. O'Sullivan was such a great professor to have for my first biology course at ECC. She gives you the powerpoint notes online, and you fill in the blanks. The tests are college level, but if you study and prepare for them, you'll do great! She has a great sense of humor, and genuinely cares about you as a person and student.

Dr. O' Sullivan is a great teacher! She knows What shes talking about. And she used very great example a to remember What you need to know. Yes her exams are difficult but you need to be there and study. She gives notes all you do is fill in the blank. And she is a teacher that cares for her students to pass! I DO RECOMMEND(only if youre commited)

Such a great teacher to have for science. She is extremely knowledgeable and is always available for help. Ask questions! Her notes are exactly what are on the test. I recommend taking 3 fifty min lecture days and 1 lab. Super detailed and helps with reviews. Not a lot of homework.

She is passionate about students and her career. This is a tough subject , but she breaks it down well. Her power points are key! You study the material given and you are guaranteed to pass. If you are lazy don't bother taking this course. She test on understanding, so cramming won't work(i learned the hard way). Great professor!!

Took her during the summer and I really enjoyed the subject matter. My only problem with her is that she graded objective answers subjectively. It really bothered me because my answer would be right, but it's not what she said she was looking for. Overall she really knows her stuff. She lets you resubmit assignments to get a point or two back.

This is a hard class to pass but she helps you and is very welcoming and shes funny. be ready to read and study its science theres alot of information! I would take her gain though. best science teacher ive ever had

I would deff. take her again and recommend her. all the info you need is in the lectures text book helps but i used lecture notes and talking to her directly. get a grasp on the info the first week youl do fine. shes helpful and really nice. she warns you this is a hard class. my favorite teacher at ecc thus far.

very nice

Yes, the tests are tough. and yes it does require a lot of studying. If you are stuck in the class, all you have to do is ASK her for her help. She's 100% willing to give youbhelp but you need to take the initiative to ask. Even on tests, ask her and she will bluntly tell you if your right or wrong. She hass great sense of humor. 100% take her!

She makes the topics somewhat enjoyable and if you study for the tests through her study guides and powerpoints you should be fine. She does provide some extra credit opportunities and labs/lab exams were fun and simple. I would take her again.

She's a great professor. She explains things very well, provides pictures and doodles to help take you through topics, and she's always available if you need help. She provides study guides and review questions. They're obviously not a comprehensive list of what's on her tests, but they're helpful in knowing what topics you need to study more on.

I gotta say this is one of the hardest classes I've ever taken, and she makes it clear in the beginning that if you don't have time for this class, then don't take it. The tests are a bit hard because you really need to understand the content of the material you read. She may be a strict grader, but fair. I would take her class again!

O'Sullivan was the best bio teacher I could have asked for. While her tests were difficult (knowledge application), she was always fair and made sure you really got the material. She was always willing to help outside of class as well. I feel as though she really prepared me for A&P. It is not an easy class, but if you put in the work it's worth it

Awesome teacher, really cares about environmental biology. I wish I had taken this class during a lighter semester as I am super interested in the subject but was taking 18 credits so I didn't have as much time to focus on the topic as I would've liked. She sounds more strict than she actually is but not in a bad way. Do the work and you'll be fine

O'Sullivan was one of the nicest professors I've ever had. She was super caring and always willing to help me when I had questions. I failed Bio 110 the first time with her and took it again with her a second time. If you're taking Bio 110, it's a hard class in general. O'Sullivan is definitely the best choice, just show up and be a good student.

Be respectful, show up on time, give her attention when she's teaching.. and you won't have a problem. In other words, be a half decent student, that's expected. Tests aren't hard, quizzes aren't hard. They're just memorization practice.

She makes it very clear at the beginning of the semester what you need to do to be successful in the class. The tests and quizzes are not difficult as long as you actually show up to class, pay attention, and study. Labs are super easy, everything is explained step by step. I was reluctant to take her class at first but it was a good experience.

Great class and professor! As long as you study you should do just fine. While I only emailed her once, her reply was prompt and she answered my question. Carefully read the syllabus and there should be no surprises. The presentations are clear, concise and organized well.

The class I took was a hybrid class, so it was both online and in person (for the labs only). Overall, she was a pretty cool teacher, and we only saw her on Fridays. The tests WILL require your notes, because she comes up with all the questions, so make sure you take them ALL. As long as you do what you're supposed to, you should pass.

Mary O'Sullivan is a wonderful teacher. Her test come straight from her lectures so don't skip class. She genuinely cares about her students and is willing to sit down with you until you understand a concept. This class is not easy, but if you show up to class, take notes, and participate, you will do just fine. I would definitely take her again.

Gives a lot of homework. I often felt I didnt have enough time to study for the exams due to all the extra assignments we had. O'Sullivan is very good at getting back in a reasonable amount of time. Being online was hard. I would not recommend taking this class online. OSullivan is a tough grader. She was very kind and communicated expectations.

Dr. O'Sullivan was good & very passionate. I took her class online & it was really well structured. I had 4 units, 4ish homework assignments each, & 1 exam each. The questions in the exams directly correlate to the lecture videos. She is kind of a tough grader, but if you ask for help, she's more than willing to. She also answers emails quickly!

I would describe her as a tough bird. I appreciated her as a professor because looking back, she prepared me really well for A&P, micro, etc. I left her class with a very solid understanding of the material. Pay attention to the details of her instructions, don't be late, take good notes, study your notes for exams. Hard but fair tests and grading.

This professor was amazing when it came to extra help! She gave me a lot of the extra help I needed to pass the class. She was very understanding and really worked with me on how to succeed in her class. Lots of homework and notes, and sadly no late work is taken but she is quick to support you with whatever help you need.

Dr. O'Sullivan was fantastic! The online class was organized & her engaging PowerPoint lectures made learning enjoyable. Assignment deadlines were well-spaced. Homework and labs are easy. My advice: do the homework, complete the labs, and make notes for tests. Everything you need is in the homework and lectures. Highly recommend!

As long as you actively participate, show up ON TIME, and have any sort of desire to obtain a degree... then you will do just fine. Yes, the course content can be difficult, but ask questions, annotate the textbook and compare your notes from the lecture, and you will be just fine. If you want it bad enough, you will work for it, do not give up.

This was a fun class, and Prof Sullivan made an impression on me. There were a lot of great projects to help with the lessons. Overall, I'd absolutely take again.
