The biggest issue that I have with this teacher is that she is very bad at explaining things to make sense to the students. She is too smart to be a teacher and she is awful at explaining tough concepts to her students. Really don't recommend taking this teacher because you will question why you did it the entire semester.

Easy class, bad teacher. Some students like Professor Dornelles, but with all her liberal comments and terrible English, I found it difficult to find her likable. Countless typos and calculation errors in her lectures, quizzes and exams (awful English). Learned most material from online. Do not take her if you have the choice.

she is terrible and speaks bad English. grades critically on everything and does not explain anything really well. tests are not huge but weighted really heavy without the contingency rule of dropping lowest one

Incredibly difficult class. Only three exams which increase in points they're worth as the semester continues. My biggest issue with Prof. Dornelles is that she almost exclusively teaches how to do problems through Excel, however does not test over Excel or allow its use on homework so you're pretty much left on your own to learn the material.

I never post on RMP, but Dornelles is so bad that I felt the need to come here and warn people. Class is extremely difficult and very little of the lecture material has anything to do with the homework. Very much like a typical academic where she doesn't know how to explain things well. In the end, your grade will suffer as a result.

Find another professor. Half the class is failing. Explanations in lectures are often confusing and hard to understand. Questions on quizzes and exams are very difficult and do not relate to learned material.

I made an account just to highlight how bad this professor is. She's smart, but awful at explaining concepts, which is the one thing a professor needs to be good at. I learned more from one 20 minute lecture from Cox than I did in the entire semester with Dornelles. She gets upset when class doesn't answer and makes awful Batman jokes. Avoid her.

Lectures are relatively unhelpful. Exams include questions that are not discussed in class. Many assignments are unintentionally difficult due to poor wording and occasional errors. I always felt I missed a few more test points than I should have due to poor question wording. Grade distribution is bad: 70% C-F's, only 1-4 A's in recent years.

She doesn't teach the class. Its an online class and lectures are given by some guy. I have yet to even see who this person is or even what she sounds like. Doesn't answer emails and if you post a question on the discussion board she calls you out for asking "academic questions" on the discussion board.

I dont even know what she looks like. Class is taught by an online guy and its extremely boring. Hard quizzes and tests.

IF YOU TAKE HER ICOURSE FOR ECN 221, GET READY TO DO EVERYTHING ON YOUR OWN! She doesn't care and will not respond to you, all the video lectures are by some other guy.

Worst teacher ever. The test is 200 points 20 questions. each test is 20% of your grade. Lectures are videos and it's a different person every time. The teacher does absolutely nothing

Extremely hard class and barley responds to emails. Extremely test heavy and the lowest test score is dropped.

Just an awful professor. Is not caring and will not accommodate any extensions even if showing proof of medical injury. Does not even teach her class and yet is so test heavy. Would never take again. Save yourself because if you take this class you are going to do teach this class to yourself.

The class was taught by using others lecture videos (not her own). She is terrible when it comes to responding to students, and it seems as if she doesn't care about her students. Overall she did nothing but allow the computer to grade students work and use other's lecture videos so she didn't have to teach. Do not waste your time with this class.

Quite literally the worst professor I've ever had throughout college. Test and homework extremely hard. Average for the first test was a 62% and she didn't curve. Lectures are taught through videos that don't make sense. Take someone else!!!

LISTEN! If you want to pass this class GO TO TUTORING! The tutor was way more helpful than the professor. DO NOT PROCRASTINATE you will fail. Do good on all the homework. Tests are difficult and homework has a bunch of mistakes on them. Learn SAS as fast as possible. You just have to push through this class. I wish I would've taken econometrics.

This is an almost impossible course. Her exams are the bulk of your grade, and she is an absolute horror at writing questions. She could write a question that says A is wrong, B is right, and then could screw up the rest of it. A) B is wrong, B) A is wright, C) A&B are wrong, D) is right. and she has so many errors. Averages first 2 exams - 55 & 61

Do not choose this professor, unless you really want to punish yourself - extremely unhelpful teaching - very hard exams - lots of homework Basically, you gotta do a lot of tutoring and spends weeks teaching yourself, if you want to get anything upwards of a B-

AVOID this class. It is the HARDEST class I've taken as an Econ major at ASU. Do no PROCASTINATE or you will FAIL. I wish I would have taken Econometrics with Murphy instead.

DO NOT TAKE THIS CLASS. Dr. Dornelles is extremely unhelpful and is not accommodating at all. Had to email her multiple times over the course of three days just to receive a response.

The semester just started and all I can say is to avoid her at all costs. Her syllabus is so disheartening & she already gave the impression that she doesn't care about her students. Make ups: Only specific deaths count, covid/sickness only count if you have documentation that you were HOSPITALIZED. She even mentions she will IGNORE your emails.

Toughest class I've ever taken. 2 of the 3 exams had failing averages, the third had a D average, all with no curve. Tutors are your best bet for passing as well as not falling behind on SAS. I got talked out of taking econometrics by my advisor - don't make the same mistake.

I had a second degree burn on my right hand that took weeks to heal. It was extremely painful and my other professors were very understanding. She gave me an extension of ONE WEEK and said that’s it good luck. How is it possible to lack so much empathy and consideration?? It took one week for me to even pick up a pencil again let alone do her HW.

This has been the hardest class I have ever taken. Horrible communication and you have to teach yourself all of the material. The professor is no help whatsoever and the tests are your entire grade. I put in probably 10 hours a week just for this class and I barely have an 81. AVOID.

The SI leaders do more for this class than the professor. When met with questions she is very rude and usually frames her answers in a way that sounds like the question is the student's problem (even if it's based on an error SHE made). The class really might as well be taught by the tutors because they care more about your understanding than her.

DO NOT TAKE STATS WITH DORNELLES If you have a hard time understanding someone with an accent like myself, you are already at a disadvantage. Homework and quizzes mean nothing. Tests are incredibly difficult with little review and are completely different then homework. She does little to no teaching in class. Be prepared to Fail. Terrible Profess

The most impactful teacher I have had at this school. Her class was truly awful, so bad that it made me rethink my entire major, and I ended up switching to STEM. This class sucks

She has a heavy accent and is hard to understand sometimes. She also talks very fast so be prepared to teach yourself. Also she is very condescending when the class doesnt understand a problem.

I should've swapped professors when I had the chance. She only teaches us through Excel, but then aren't allowed to use Excel on the exams, her TAs didn't even know this. The homework is basically useless and so much work, it didn't bump my grade up AT ALL. She does drop one exam, practice exam, and homework.

Hard to understand at some points. Uses excel for explanations during lecture when you can not use excel on the exams. She offers extra credit in class but the answers must be correct, if you're struggling with the material this isn't very helpful. Overall, seems to be too laid back and doesn't really care about the understanding of her students.

Do not take her for ECN 221, her lectures are too fast to follow and the amount of time spent outside of class to prepare for exams is crazy. Hard to understand accent doesn't help either. Select literally ANYONE else.

STAY AWAY, she teaches in Excel however it's not allowed on the exams which makes no sense. On top of that she's probably the least accomodating and caring professor I've ever heard of. It's so bad it's honestly laughable. Just take an icourse or anyone else.

Do not take the in person class with her! She teaches the in person kids how to use excel to solve the problems but will not let them use excel on the in person exams. However, she lets the online kids use excel for every exam. In person kids barely pass the class while the online one's pass with A's

There are no good teachers for the ECN221 class, and i selected her because she looked better than the rest. There isnt much homework, but when there is it has no relevance to the material in class. Her lectures are way too fast and the essential formulas and variables she just skips over. The whole class failed the last test. Dont recommend!

It was honestly sad that I am writing this poorly of a review about a teacher but in my 13 years of schooling, I have never been taught by a more unsupportive professor in my life. It's pretty hard to understand professor Dornelles and the content that she teaches in class just isn't that simple to get the understanding of it on the first try.

She is totally awfull...Never go for her guys trust me . I screwed up my whole life because of her...

She doesn't know how to round, I had to correct her syllabus quiz, lectures are terrible. Reads off the slides but doesn't speak in a way anyone can understand so nobody pays attention. Additionally, she quizzes you at end of the class (unexpected) without time/instruction, setting her students up for failure. Half of class dropped halfway through

Sinister. Absolutely unhinged. Incredibly tough professor who has confessed that only around 60% of her class passes each semester. She has no empathy for her students and cannot take accountability for her miscommunication and her mistakes in Canvas. She shames students for not understanding the material during the class quizzes and lectures.

Toughest class taken at ASU. Prof. Dornellas is no help at all. L class and L Professor.

PLEASE DO YOURSELF A BIG FAVOR AND AVOID THIS PROFESSOR AT ALL COSTS. SHE MAKES THE CLASS HARDER ON PURPOSE AND IS EXTREMELY RUDE TO HER STUDENTS. IT'S LIKE SHE WANTS YOU TO SUFFER IN ORDER TO PASS THE CLASS.

I can't un-recommend this professor enough but she is the best option for Business Stats currently. If you go to class consistently and do well on the in-class quizzes you will end up with enough extra credit to pass. She does not teach well and blames her own teaching errors on the students. Homework isn't too hard but the exams are.

I swear half the material on homework and tests isn't covered in the lectures. Exams require you to round and answer every part correctly with no wiggle room Practice exams are on webcam and are worth 20% of you're grade.

Such a hard class I thought I was gonna fail but the extra credit came through. Lectures did not prepare enough for the tests. Practice tests did help with the exam but had to teach myself how to do them. This class really affected my mental health. Professor put the wrong answers as correct on assignments.Try to avoid this professor if you can.

Honestly the worst professor I have ever had in my college career. I have never felt compelled to rate one of my professors until taking her class. Having to retake this class because her lectures were so useless. Already doing so much better with my new professor. Prides herself on how hard the material is and that her students are unable to pass.

Please do not take Adriana Dornelles! I spent 2 hours just try to get full credit in her syllabus quiz. She only gives 3 attempts for syllabus quiz! And you can't look at your previous quiz unless you finished all attempts. She gives in-person quiz for less than 10 minutes and if you are not ready or not prepared before hand, then you are screwed.

This teacher should serve jail time. She enjoys demoralizing students

Don't take this professor! she has a bunch of in class quizzes that's 25% of your grade and it's very hard to get full credit because everyone has different questions and time she gives is very short, you can't even ask your classmates. You won't get a high grade easily.

She pop quizzes you every single lecture and gives you sub 5 minutes to finish the quiz, which is nowhere near enough time.

When I read rate my professor reviews, I usually take it with a grain of salt because sometimes people can be dramatic but not in this case. I leave this class more confused than when I walk in. If you enjoy panic attacks then this class is for you. If you want to survive you need to fully know the topic before class.

(ECN 221 iCourse) she is responsive and approachable but test questions and practice questions are consistently worded terribly, and often ask a different question than what the 'correct' answer usually represents. Absolutely avoid this class.

Please don't take this professor, I repeat do not take her. We should complain to ASU authorities that we are paying so much fees and these type professors are going to teach. She doesn't know what she is teaching she just mug up, PLEASE ASU I BEG YOU YOU SHOULD REMOVE THIS PROFESSOR, NOT AT ALL WORTH STUDYING WORST TEACHER AT ASU

save urself the tears honestly. halfway through this semester and i just withdrew from the class. not manageable, horrible exam scoring, and not to mention, exams are proctored through honorlock. take this class with ANY other professor if you want to avoid teaching yourself the entirety of the curriculum.

Good luck if you have her. Haven't ever punched my wall as hard or as much since I started this class. Cant understand her in class and lots of her slides have typos.

This chick is the worst teacher ever. There is no reason why she should be a teacher. PLZ don't take this class you will fail.

If you were considering taking this class with her, do not do it. I have never struggled to get a B in school, yet I am on the verge of failing this class. The homework is unreasonably hard and it does not give any assistance or direction on why or how your answer was wrong. The tests are loaded with questions that follow up the previous question.

Easily the hardest class I have had to take and the professor makes it so much worse. Lectures make no sense and they are set up in the worst way (no fast forwarding, leaving the tab pauses the video, can't make the video full screen). I had a 4.0 GPA last year and I will be lucky if I get a C in this class. Take literally anyone else.

There are not words to describe the anguish I felt taking this class. I have a 3.8 but I will be lucky to get a C in this class. Her lectures are borderline unwatchable so I found myself teaching each chapter to myself. This makes the tests a true nightmare and your whole grade depends upon them. Worst class and professor I've ever taken.

With all of your might do not take this professor. The class was extremely difficult and her lecture really didn't dive into depth. I was teaching myself each and every unit and it still wasn't enough. The first two exams aren't too bad but the third and final were some of the hardest I have ever taken.

I cannot stress enough, take literally any other professor if you possibly can. Graded practice exams are absolutely nothing like most of the actual exams and the homework is basically useless compared to the exams. Terrible professor who prides herself on having an insanely hard class and not really sure how she still has a job at ASU.

This is the hardest class i have ever taken. I had a 4.0 and have never gotten a C in a class before till now. The practice exams are not like the actual exams and the wording is terrible. She posts so many lecture videos, but they are not helpful and neither is the homework. Take literally anyone else.

This teacher is easily the worst teacher I have had so far at ASU. Very disorganized, 1/3 lectures aren't even her on her modules, and her test questions have nothing to do with the concepts presented in the lectures given in the first place. Her answer keys for practice exams and exams rarely correspond with the correct answer. DO NOT TAKE THIS!

It is nearly impossible to receive a decent grade in this class. The grading scale is extremely unfair with a heavy emphasis on exams and GRADED practice exams. Her lecture videos are extremely lengthy and often skip over key steps or are missing information. Feedback on practice questions is practically nonexistent. HW and exams DO NOT correspond.

For having a 20 page syllabus, this is by far one of the most poorly constructed courses at ASU. Coursework and lectures don't even cover what is asked on exams. Her strict grading makes it nearly impossible to receive a decent grade. Overall, the concepts are not difficult but the teaching is absolutely awful.

Professor Dornelles's ECN 221 is one of the most unfair class I have ever had, the assigned work totals to only 15% of the total grade, the "Practice Exams" she gives is MANDATORY if you want to have a passing grade. Not only is the grading harsh, the exams are just as bad, as the coursework do not teach you the information in the exams.

Very tough professor.

To simplify my experience with Professor Dornelles my dad passed away durning finals week the semester I had her. I was given a 2 day grieving period and was still expected to take the final. Do not take.

Listen to the reviews, she seems like a perfectly nice lady outside of class but her teachings inside of the university are not the best. Class overall was extremely confusing for me and she did not help the digestibility at all. Tried to take a chance and take someone with low ratings, will not make the same mistake twice.

Horrible teacher. I literally have never recieved a B or below in a class EVER. I got a D in this class. The homework and practice quizzes do NOT prepare you for exams. I studied for days leading up to the exams and the highest grade I got was a 40%. In person classes are mulitple choice and have cheat sheet, she does not allow either. DON'T take.

WORST PROFESSOR!!!!!! syllabus quiz is 5% and 17 questions with two attempts.

This is the true meaning how not all online classes aren't the best

This class is awful and extremely difficult. Mentally draining.

This course was insane. A C+ may not be a failing grade, but I have maintained over a 4.0 every semester at ASU. Avoid at all costs, the tests are brutally difficult, use different symbols and terms than she does, and the homework is barely related, but it doesn't matter - it's only 15% of your grade anyway. Practice&exams are 80%...closed note.

Lectures are horrible, she doesn't seem to be aware that the people taking the class have not already learned the topic prior to attending her course. She does not utilize any technology during her lectures to show how a problem is worked out, rather will just quickly talk through it instead.

Four practice exams are 20% of your grade, two require Honorlock, and each has only four attempts with 15 alternating questions (as redundant as it sounds). Real exams are 60%, closed-note, and also use Honorlock. The ‘study guide' is just a PowerPoint saying to review modules and homework, followed by vague list of topics.

The semester is graded heavily on 4 exams which the lectures do not prepare you for. Tests are different than homework using different symbols/ wording. Extensions are not offered, even for technological issues, she does not care. The only lessons I understood were using another professors videos. I'm a B+ student & have never done worse in a class
