Great teacher, always available for questions and help. Fair, honest and dedicated instructor.

This class is very easy if you show up and take notes. He is the sweetest guy and really helps his students. He is the easiest of all the science teachers.

Hes awesome

I didn't take him for lecture, but his lab is easy. Go to class, do the lab, he'll give you 10 points for the lab, and then you just have to remember what you did in the labs in order to pass the tests. We get to leave early from class most days.

That's why we call him "Easy A"!!

Alex does a great job. His tests are hard but you learn a lot and he grades fairly. Do the extra credit and get a B on all your tests and you get an A in the course. Lots of work for one unit. Alex is real cool and he'll help you out any time.

Grades his labs for completness not correctness since he gives the key to every lab. The tests are really tough, so know your stuff. Not a cumlitive final thank God. Alex is a super nice guy with a lot of good information, you'll learn a lot. Holly is still the best teacher in the dept...

If you show interest he'll be much more receptive. If you're not organized choose another instructor, because he doesn't baby the class AT ALL. If you are not following the syllabus, ouch! He won't remind you that a paper's due or it's time to turn in the log. "Easy A Amigo"? More like, "Personal Responsibility Amigo"!

Great teacher. Really likes to help his students, but only if they ask and try hard. Will really work hard for his students. Tests are tough but the class is very interesting.

Oh Dr. Amigo... Interesting character. He speak a bit like some guy from zoolander or something. I thought he was a great teacher. I do admit he does have an air of arrogance to him though, unless you show genuine interest. he offers extra credit and is extremely clear in his lectures. I didnt want to take the class at frist but im glad i did

Goes over everything and then goes over it again. Makes sure you learn stuff. Repetativeness a little annoying but makes life easy. Open not and take home tests

A lot of work. There are 4 tests (50 multiple choice, 3 short ans., 1 essay), 3 assignments, 3 quizzes, 3 reports and 3 essays. Bonus points every day you go to class. Goes over material very well making it easy to get an A. Makes it easy when you go everyday. Need blackboard access (quizzes and tests taken online (open everything:) Fair grader.

Dr. Amigo was a great Professor I thought. I liked that I was held accountable for my own education. He does not baby his students, I felt we were expected to be responsible for how much we chose to get out of his lectures. I enjoyed that his lectures were relevent and that we applied what was taught. I loved his teaching so much I am taking ES1

Took online class from him. Do NOT expect him to send reminders of assignments or tests due, you need to check Blackboard and follow the syllabus. More interested in concepts. Only complaint is no real study guide for tests.

stay on top of the exams,some stuff he gets from there without saying anything

Dr. Amigo's tests require you to be able to explain the material as if you were teaching it. He raises your grade one whole letter for completing all in class extra credit assignments. If you can explain all the key terms on his ppt's, you'll do fine on the exams. His sketches are helpful, and he completely answers all questions. It's really on you

*ignore slackers comments* Alex is very helpful and quite clear. There ARE study guides, called NOTES people. A couple of the tests require more studying than others because there are a lot of terms to know. I recommend him. I actually like science now.

Yes, he has a slight air of condescension and he does tend to point out others' flaws in logic, but overall he's a good teacher. He knows his stuff and his class is structured simply. Be prepared to take responsibility for your own work - you ARE in college - and his voice makes you sleepy. If you need help, ask for it. He's happy to help.

he tells you to read 40 pages out of the textbook, then gives you 2 random questions from that reading, and that is like half of your grade. the other half is based on a very difficult scientific report that half the class failed. his class would be a lot better if he taught the chapter before he quizzed studentson the material, instead of after.

I took his esci 10 class, and now I am in his esci 3 class. He is one of my most favorite teachers at Sierra. He has a masters in teaching, and he knows what he is doing. His tests are straight-forward. The questions are taken straight from lecture notes, which he gives you, and if most people miss a question he gives everyone credit for it.

He is not condescending in any way. He cares about his students and is flexible with his teaching BASED on each class.

Great teacher. Need to put in the effort and make sure to ask questions as they arise. Come to class it isn't hard to to get a B or even A if you do.

A great online instructor! If you read the lectures and the assigned book chapters then the quizzes and exams aren't difficult. Dr Amigo gives plenty of direction regarding expectations on reports and written exam questions, as well as providing helpful feedback on student answers. He obviously enjoys teaching this subject.

I love professor Amigo! His lectures are organized and easy to understand. He is not a very hard grader. Yes, there is no homework so your grade is based of tests and..what EXTRA CREDIT. just for being in class. Show up and you will do fine. If everyone misses something on a test he gives everyone points for it.

AMAZING TEACHER!You would be hard pressed to find someone on a UC campus with as much background and education as him! He should teaching at Berkeley or UC Davis! Take him while you can! i hated Geo before and to this day when I am traveling or hiking I can recall things he taught me. I plan on taking him again just for fun! Great guy Great Prof

Take his online summer class. If you fail this class or get anything less than a C+ you should seriously consider if college is for you. Does not get any easier than this online summer class and I am not a science major. Open book quizzes and tests. I spent max 2 days a week working on this class. SO EASY

First of all, let me just say Alex is the best professor I've had at Sierra College. Don't let all these bad reviews fool you, if you're a serious college student who takes his/her work seriously there is a lot to be gained by taking one of his classes. To those complaining about online instruction, consider taking an actual class on campus.

Don't be fooled by these bad reviews. If you are interested in Earth Science, he is a helpful and knowledgable teacher. If you're looking for a class that you can "float by" without really having to do anything or show up than look else where or stop going to college. He is a good teacher who actually knows his stuff!

For Physical Geology,great teacher. Makes things easy to understand.I don't understnad the comments about him being condescending. Non-cummulative final :), no quizzes, 4 tests thats it! Lots of extra credit, wants his students to succeed. One of my favorite teachers so far, learned a lot in his class. You WILL have to study though.

Took this class over summer, lectures were available over the assigned readings. Occasional questions on tests were open to interpretation but overall easily understood. Easy A, skipped last report assignment as it was optional and I nabbed a 97 without even trying.

Loved this online class. Clear syllabus & firm due dates given beforehand. Independent work just print (highly suggested) and read lectures before taking the 5 small quizzes and 7 exams. Tests contain info right in the lecture (emphasis on printing it!). Never communicated with Prof but seems to fairly grade 3 small reports (2 mand., 1 for E.C.).

He is an awesome dude, just takes a little getting used to. I honestly don't understand how people have given him bad reviews. I would absolutely take his class again. Also if you have questions he is very willing to explain, and will stay after class if your questions go beyond the course material.

Alex amigo is a easy teacher and if u wanna pass his class all you gotta do it do all the labs which he gives you all the answers to. I didn't do very well on the test (3 test) and I still passed with a B

I loved the format of this class, quiz to prep for class then class, then exam and done.. no having to go back and forth and stress about finals, each subject concludes when you turn in your weekly exam. Great Instructor!

Alex is a wonderful teacher. Sometimes the way things are worded are very clear, but if you ask he will clarify for you. I really feel that he cares about his students and he establishes really good rapport with you if you talk to him. He can sometimes go a little of course when he is doing a lecture, but it is usually relevant or interesting.

I took this class online and all in all I found it to be a great class. Alex is very clear about what he wants in your papers and even gives examples. I didn't use my textbook a lot but he does reference it in his lectures quite a bit so it was nice to have it for that and also exams. I would definitely take a class with him again.

I learned so much in this class. Prof. Amigo makes you work for it but is an amazing professor! He was always clear on the assignments and tests. I am not a science buff but this ended up being my favorite class! He was awesome! Must attend class and keep up with homework but definitely worth it!

Professer Amigo was great! I was nervous about taking Earth Science but he did a really great job. His quizzes were all from the book so just make sure you read the chapters. He also responded to any emails I sent him if I was having trouble. I would definitely recommend taking his class!

Pofessor Amigo is awesome. His lectured are long but he uses the time well. I've never left class without a clear understanding of the topic. There's a lot of quizzes/exams but he is extremely fair on the grading. The quizzes/exams are after each topic covered so that you can be tested while you still remember. He is very easy to get along with.

I had him for Earth Science Lab and really enjoyed the class! He is really nice and gives clear directions. Do not know what kind of teacher he is in lecture, but he is a great LAB teacher! Recommend.

I took his Earth Science Lab and I must say he's one of the best teachers I've had. He makes sure the students truly understand the concepts before starting our lab and is always willing to explain further. I wish I had taken him for the lecture part of Earth Science. The class environment is very relaxed. Labs can't be made up, attend class.

I took Energy, Environment, and Climate with Alex and he created it himself at Sierra. I thought he was a great teacher and I really enjoyed the class. It was pretty easy and the information was fascinating. It could get boring at times. I would recommend.

I had Alex for both his online lecture and in class lab. He was a blast! He was hilarious and made being in his class super enjoyable. In class - Only 3 tests, based off the 12 labs. Walks through the labs with you then lets you leave class once you're finished working. Would hands down take him again and recommend him to everyone I know!

SAVAGE. Dude is fine by me. I passed the class with relative ease. Good sense of humor.

Dr. Amigo is great, he expects you to learn and he goes into depth about everything. He's an expert and lays it all out there in order and it's up to you to study. He gives a lot of extra credit but also is semi difficult with grading. I really enjoyed his class, very clear and concise.

Alex Amigo's online class is great. All tests are based off the lectures and there is even extra credit.

Great teacher who is very helpful. Gives feedback. You will need to put In a bit of work but its not terrible like some classes.

Alex is great. Took him for both online and lab. Super easy class if you do the work and pay attention to what he wants. Definitely recommend him over any other Earth Science professor at Sierra. He knows his stuff, and you will learn a lot and have fun in his class with no pressure. He is very involved, responsive, and wants you to succeed.

I took him for the earth science lab and it was really easy! I learned a lot from him that helped me in my regular earth science class and he gave us good preparation for the tests

I took intro to Earth Science - ESCI 10, online class. Very clear instructions. I passed with a B just by reading his weekly 3 pages lecture and power point. But reading the book as well definitely helps. He also offers 20 points extra credit which could raise your grade a letter. Great professor and provides appropriate feedback and grading.

This was a great science class. Alex is an awesome professor and the class was nicely planned out and as long as you take the quizzes and tests you will do very well in the class. Take this class

I rented the textbook, but I really only used it in the beginning of the course, since I could find the answers in his lectures 97% of the time. You have 7 exams, 5 quizzes and 2 (small) reports , they are extremely easy if you actually do the reading. He offers extra credit, consisting of a 3rd report and practice quiz. Do your work and get an A.

Clear expectations. Always available to students. Tests as you go on the previous weeks work. No cumulative final!

I took Prof. Amigo's Earth Science lecture class online over the summer. Due to the fact that it was only 8 weeks long, we did have 2 assignments due per week- either a report, quiz or exam (varied in combination by week). There are online lectures, which I recommend you print out to use for quiz/exams. I would recommend renting the book if you can

Alex classes are very straightforward. Theres a lot of extra credit point available, show up to class and do the in class assignments and youll pass no problem! Sometimes the exams for lecture are confusing, but he goes through and if the majority of the class got an answer wrong he gives credit back! Really a wonderful professor!

Took Earth science with the lab. Fun class, a lot of group work! Tests are a bit difficult and you have to go to class, if not you'll miss a lot of information. Otherwise, great teacher and fun class.

Took his Earth Science class and also the lab with him. Really enjoyed his class but the tests can be a little hard.

GOOD FOR NON-SCIENCE MAJORS. I took this class as an incoming freshman and it was by far easier than any class I took in high school. I used the textbook for pictures but honestly you could get away without it. 7 unit exams, 2 short papers (3 paragraphs long), 5 quizzes. Extra credit available through report and syllabus quiz. Very good experience.

I took his online class and it was very straightforward. You just read the lectures and take the test. I recommend the class to anyone who wants an easy A and some interesting knowledge about our planet.

The most organized professor I've ever had! I found tests to be heavily based on lecture and PowerPoint notes. I found the textbook to be very difficult to understand. What worked best for me was to read/highlight/take notes from the lecture/PowerPoint and then look at the textbook charts that were mentioned in the lecture. Keep up with reading!!!

I took Professor Amigo for Geography during the summer & loved his class! His online set up is VERY organized & easy to navigate. I didn't need to use the textbook at all! The lectures he provides are everything you need! He is professional & easy to communicate with. I appreciate how he treats his students like adults. Welcome 2 College ya'll!

He's the most fair teacher I've ever had the pleasure of meeting. He definitely wants every student to succeed. Don't be afraid to ask questions and be sure show up to every class. His labs are a lot of fun, and again ask questions! He's always ready to explain complex concepts in a way that you can understand if you just ask.
