Thank you for viewing. ■ Item Condition This is a problem set for high-level physics by Mr. Sonda from 2018. The text includes answers and has no writing or markings. I will also include the notebook where I answered the questions (there are some notes by Mr. Sonda in the commentary section), but please let me know if you don't need it. When shipping, I will black out the name on the notebook, so please be aware of this. Please note that this is not a notebook with board notes other than the problem explanations. ■ Additional Information I live in a pet-free and smoke-free environment. Please understand that this is a used item before purchasing. ■ Comments If you have any questions, please feel free to comment. Instant purchase is also welcome.
