This is, in my opinion, the best course for first-year science students not majoring in physics, especially for life sciences. It is still a significant learning curve from high school and people absolutely still fail if they fall behind, but if you keep up with the course and have a strong math foundation, it should be pretty easy to get at least a 75% in the course.
Covers fluids, simple harmonics, waves (travelling, standing, sound) with interference, and nuclear physics. A free textbook is provided but the content is more complex than what this course covers. Course requires absolute mastery of algebra and trigonometry, and (very basic) calculus for deriving velocity and acceleration (though MATH 100 is a corequisite for this course so you should be familiar with these problems then).
Professor Iqbal is an amazing and enthusiastic professor, using lots of demos to teach the class. He does not take attendance or mark participation so you can skip lectures without consequence if you catch up later.
Attend weekly tutorials, as they are very easy marks (marked for effort). However, you will work in small groups, so keep up with the material so you can contribute rather than letting your group down. Homework is also mandatory but marked for completion, making it a very easy way to rack up free points.

Great course , not difficult . You will pass as long as you understand all the contents . the exam are a lot more difficult than the midterms and quizs but it only takes up 35% so it wont be a problem as long as you have great grades for the remaining parts . The midterms are quite easy , and exam cheatsheet is quite useful .
Edx readings , tutorial session , Edx assignment .each week Five quizes , and two midterms . Most of them are easy so it isnt impossible to get full marks for most of them.
Nice prof , extremely helpful and willing to help us for all types of issues . Sometimes he makes some jokes related to the content .
Complete all the assignments and quizzes on time . Attend help sessions or ask questions on Piazza if you encounter any problems . Most TAs are helpful .Make good use of your exam cheatsheet . Watch the video lectures occasionally .( Iclickers not for marks and no attendance will be taken )

It’s an easy class if you do the webwork assignments on time on your own
A fairly new prof, had the lowest section avg but was nice at teaching

I loved this class. Dr. Iqbal was so caring! You definitely could tell that he wanted students to do the best as possible. I watched all of Dr. Hallas' lectures, as well as some of Dr. Plotkin's. Together, I feel like the lectures were a very good indicator of what would be tested on quizzes and tests.
I never did a single textbook problem. You may or not need to as well. I took Dr. Iqbal's advice and focussed on redoing exams, quizzes, tutorials, clicker questions, etc.
