Interesting material and good breadth. The difficulty level varies a lot between weeks - some weeks are very in depth while others seem like filler in comparison. There are a lot of equations introduced which require more knowledge of physics than I had expected from the course description and seem to be beyond the scope of an introductory course. Fortunately, following these equations is generally not necessary to understand the course objectives, but it does make following the lessons needlessly complex. Additionally, some of the quiz questions require memorization of specific numbers/values that are only tangentially related to the week's topic and don't help to further understanding of the subject matter.

The course is good, although too general. It could use more challenging exercises and mathematics, more in line with a course in Particle Physics in a standard Physics curriculum.

there is a translation issue in some videos especially the ones with others (except Martin and Mercedes) and also the explanations are a bit monologous

Unassuming about prior knowledge. Quizzes oriented to beginners, lectures to grad students. Confusing, but fun nonetheless.

Introductory course and little prerequisites. It is good in general but I still got lost in some lecture videos.

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

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.

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.

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.

Very poor language. Poor explanations and poor teaching overall. There can be lots of improvement.

Lacks the flow. Emphases on information than knowledge.

Didn't enjoyed the lectures.
