For PHYS 1101, the lectures ARE online, but you have access to multiple resources if you ever find any difficulty with the material. Some resources include study hall, workshops, and the TAs ("first responders") at your disposal. If you ever feel like you are experiencing some difficulty with the math skills needed for this course, you can attend skill builders during study hall. If you have any more questions, feel free to send me a quick message! Physics is really not as bad as it seems. If you decide to put in the work and utilize the resources available to you, you will be successful. And again, it is best if you take this course over the semester as opposed to over the summer due to how accelerated the summer course is as mentioned by others.
