  • I don't understand how this lab course still exists. It is to my understanding that this course is going to be dropped in the year after mine, and initially I was confused about this. However, after the first two labs, I understand why exactly nobody seems to enjoy this course although there is a 57% liked rating. The lab manual is honestly too vague to retain any useful information (if some), and for some reason there seem be instructions which are OMITTED from the lab manual itself, but still graded. Why? I don't know, but I do know that this cost me the process of writing the actual report. I cannot stress enough about how thoroughly I am unenjoying this course, but seriously, this is…

  • The lab course wasn't as bad as PHYS256 was, but it still sucked. The labs are boring and finicky, requiring you to hunch over and look through small lenses, make tiny adjustments on crappy instruments, and often count hundreds of minute details. Feedback was ok and the lab reports themselves are okay. However, they took a very long time to be graded. Our TA often told us that reports would be graded by the weekend, but very often the reports were released on Tuesdays or Wednesdays, costing valuable time (reports are due on Fridays). And our section got lucky - another section got Lab 3 (due in early November) back just a week before winter holidays. In contrast, the late policies are very…

  • Overall, I was quite disappointed with the way this lab was being run. The labs were extremely time consuming and difficult. Additionally, it felt like the TA's were nitpicking certain areas of the report when they were marking it. For example, in my first lab report, I received a score of 14/20. I had noted the mistakes that I had made in the first lab report, and I had incorporated the feedback into my second lab report. However, the TA's still found areas where they could deduct marks. Furthermore, there was not enough time given to write each lab report. I would recommend taking this lab with a reduced course load. Additionally, the lab exam was also quite difficult. This was my very…

  • Labs take quite some time to write. I took it only on Fall 2020, it was very useful to understand the content of PHYS 256 (this course alone without the lab is just a mess and don't take it unless you need to). I feel like I learnt much more from this lab than the lecture course

  • Lab manual is cryptic but the labs are fun when you figure them out. The 2nd lab was very hectic and seemed to have too many things to do in the allotted time, but all the other labs had enough time for you to complete them.

Which Physics Lab? 5 points, 4 comments

“For my program, I need to take Phys360A&B (Modern Physics Labs), but the prerequisites for those are 3 year-two physics labs of my choosing. …”

u/KaliumNa: “… PHYS 256L is best taken with PHYS 256. It covers a lot that is in the lectures. Both courses are 5 labs each. PHYS 232L lab reports are due next day. PHYS 256L are due (I think) one week later. …”
