Not the worst, also not the best. He went way too fast on so much complex material and made those things more confusing. Also would take off more points on regrade request exam questions (he did this on the final exam). Also, there was no curve. A bit disorganized and didn't follow his own schedule.

He is def there just for research, his lectures are REALLY fast paced especially for harder topics. Only provided a practice exam for the first midterm, the rest he provided questions for each chapter. He didn't give us practice for an entire chapter until after the exam for midterm 3. Overall not a bad professor, choose lewis if possible.

Truly awful professor. All the midterms had NO partial credit which is absurd considering the other professor teaching the same course had partial credit on his exams. He basically throws you in the deep end and says "good luck". If i could do it over, i would have NEVER chosen his class, absolutely no resources either. Choose a different professor

His slides are good but he goes through them in a way that is way too rushed to actually learn and uses extra time to talk about his research or end class early. Tests are fair, but he often doesn't provide practice tests or chapter questions, so all u have is the textbook to review and he'll never post grades/materials by the time he says

Do not take this prof for 109A. Terrible introduction to ochem. Disorganized, poorly paced, confusing. Lecture slides on canvas did not align with the lecture slides he actually presented. Treated it like we already knew the concepts instead of it being our first time seeing organic chemistry. Only succeeded bc of the textbook.

He was a pretty chill professor for the first few weeks but when we got to the tougher chapters he speed ran them during lecture and oftentimes made mistakes during lectures and in his own practice problems making everything so confusing. I learned most of the material on my own. Overall way TOO fast, brief, contradicting, and confusing lectures.

It's OCHEM so it was a lot of content for sure, but he did a great job providing resources and the tests were really fair in my opinion. Overall I would definitely take him again even though the pace of the class did go fast sometimes.

Javier is really approachable and always willing to help. His office hours are so helpful and he actually takes the time to make sure you understand. His midterms are fair, if you do the textbook problems, go to lecture, and go to office hours you'll be fine. He does lecture fast, but reviewing the book or going to office hours makes it manageable.

Love Javier! GOOD lectures and every Friday he yaps a little about something he's passionate about before lecture. I always check my exams to make sure it's graded correctly and every time I submit a regrade, he is lenient when it comes to partial credit. Pay attention in lecture and do all the book problems and u will be so good for the tests!!!

LOVED READ!! His Friday podcasts made my day, and his lectures made sense to me. Though sometimes he would speed through things and have you read the textbooks but overall he is a great prof. Love helping his students and is very personable. Midterms were easy but final was HARD.

Javier is fantastic: Super fun and approachable guy who made ochem feel accessible. Tests were very reasonable and there wasn't much homework. I did have to use the textbook for clarity, but that's why it's there in the first place.

Relatively mediocre lectures but at least has some personality. Practice exam keys are not super well written and his TAs and LAs did the majority of the good preparation for students. The class is nowhere near as hard as people make it out to be and should not be scary, though, one may need to put some effort into understanding the material.
