- Office hours for instructor: MWF 9:30-11:30 AM.
- Syllabus for the course. The Provost Office has put together a Syllabus Attachment to assist the student. It lists and provides web links for many elements that are important for a student.
Resources:
- Assigned Textbook:
- Lectures
  - Lecture recordings from 2021 Spring as a YouTube Playlist
  - Formal Lecture Notes: This is not a substitute for a textbook.
- Quizzes and Homework
  - Equation Sheet: While working on homework you can use any reference, however, aim towards limiting your reference to the contents in the Equation Sheet.
  - Submission of Quizzes and Homework will use SIU MyCourses.
  - Practice problems: Available at Binapani Academy. It is a free service and requires a one-time registration, Code: SIUC2025. My colleague, Subtata Bal, has developed this platform from a collection of questions and content from more than twelve semesters of my teaching PHYS-205A in SIUC, to make it available to students to aid their learning. His team is developing AI tools to find new ways to make these resources aid student learning experience. This platform is in active development.
- Exams
  - Old Exams are available in Past course webpages: [2025F, 2025S, 2024F, 2024S, 2023F, 2023S, 2022F, 2022S, 2021S, 2018S, 2017F, 2016F, 2015F, 2014F]
    A recorded review session serves as a 'Video Solution' for an exam in another semester.
  - Equation Sheet
- Miscellaneous
  - Errata: List of errors spotted in videos and hand-written notes has been collected here.
  - Physics Help Desk Schedule. Contact Shannon Ketteman (mari.ketteman@siu.edu) at the Physics department office for updated information.
  - Tutorial: PHYS-206A serves as a Tutorial Session for PHYS-205A. Concurrent enrollment in PHYS-206A is recommended.
