Interesting material, great instructors, but .... the monotonous, not-so-enthusiastic delivery may put one off.

try simplifying the course a little more

subtitles can be improved.

Although the course covered a wide range of topics, the mathematics were beyond my understanding (as a 10th grade student) and the accents were hard to understand and annoying from time to time. I had to learn most of the topics from other videos on YouTube because the topics were not simplified enough for me to understand. I would say you should enroll for free and have a look at a few videos before purchasing the course like I did. Overall, it was an interesting experience.

English hard to understand, and content impossible to follow. Even though, I am quite proficient in Quantum Mechanics, this course introduced variables in equations, without defining them. It takes thrice the time of the video to fully understand the content of the video.

The topic is highly interesting but unfortunately, I have to agree with the negative assessments:

he presentation style is inadequate for learning

bORING

Very poorly presented course. Despite having completed quite a number of coursera courses before, and even being already familiar with a good deal of the preliminary material in this one, i soon abandoned it due to the inadequate and scrappily prepared presentation of material. Mercedes Paniccia in particular speaks in a virtually unintelligible expressionless monotone with no explanation or elaboration to relieve what amounts to little more than a list of definitions and bald statements such as can be found in the glossary section of many textbooks. I would strongly recommend finding an alternative course devoted to the subject or maybe seeking out a readable textbook.

Great subject with a lot of information unfortunately not very easily accessible because of the way it is taught here. The video lectures are lack lustre with tutors reading text unenthusistically from the slides. Some resource links do not work and seemingly have not done so for years. One tutor's English accent is hard to understand unless you run the video playback at 0.75 and have a copy of the transcript to follow. All of this makes learning tedious. I gave up at week 4. Singularly the worst course I have taken on Cousera.

Selected portions were good; other sections were plain horrible; difficult to understand the lecturer (not the topic; rather the english). For an english speaking course, videos in another language were not useful. Lectures provided no insight, pure reading from a lifeless script. Wording of problems had lots of typos, and questions were ill formed... I would not recommend this course unless it was cleaned up.

It must be taught by someone who can speak english clearly. Sorry but I couldn't understand what Mercedes Paniccia spoke, which made the course even more difficult to understand. There are subtitles but it's not possible for everyone to put that much effort. This issue must be taken seriously to make this MOOC much better.

'Teachers who make physics boring are criminals' - Walter Lewin.

Professors are just reading notes and explaining nothing including theory and derivations. Nothing has been explained intuitively. Particle physics is one of the most interesting fields in this discipline but this course has done injustice to it.

this course is not at all suitable for someone who is here to learn particle physics. the teachers assume that we already know what all the symbols mean and its like they are not teaching but reading.

The Professor might be a brillant scientist, but as a teacher he is not that bright. Few others have developped the poor course at length previously. No need to repeat!

Didn't enjoyed the lectures.
