What are Student Hours?
The main purpose of student hours is to offer students an opportunity for one-on-one interactions with the instructor outside of the regular class time. Here’s what typically occurs:
• Scheduled Timing: The instructor will announce the student hours at the beginning of the semester, including the time, day, and location. These details can also be found on the course syllabus. Each Sunday, the student hours for that week will be posted as an announcement on Blackboard, which also gets sent as an email.
• Questions and Clarifications: Students come with questions about lecture material, readings, assignments, or topics that they find confusing. It’s an opportunity to clarify doubts or delve deeper into a subject.
• Assignment Feedback: After grading, students might want to understand mistakes they made on assignments, exams, or papers. During student hours, instructors can provide more detailed feedback and suggestions for improvement.
• Discussing Grades: If students are concerned about their grades, they might meet with the instructor to understand how they’re performing in the class and get recommendations on how to improve.
• Building Relationships: Beyond just academics, student hours can be a time for students to get to know their instructors better, discuss their academic interests, and potentially seek guidance about future courses, research opportunities, or career paths.
• Course Logistics: Students might have questions about upcoming assignments, exam formats, course policies, or other logistical aspects.
• Additional Resources: The instructor can recommend additional resources for students looking to further their understanding, like books, articles, or other supplementary material.
• Personal Concerns: Sometimes, students might discuss personal issues that are affecting their academic performance, such as health concerns, personal crises, or other challenges. The instructor can offer support, understanding, and direct students to appropriate campus resources.

How to schedule a tutoring appointment with OSS?
How to study?
Use practice exams as a study guide. Start working on the practice exam earlier. Make sure you understand and remember the steps of every problem. If possible, do the practice exam multiple times.
In class: Engage and take notes. Answer questions. Ask questions.
After class: Review the notes. Watch recordings if needed. When you watch the recording, you can control the speed. Stop every step to think through the math. Make sure you understand every in-class example. If you have questions on some steps of the problem, ask Suky. Visit office hours or if you are not available during my office hours - email me to schedule an appointment. Your exam questions are similar to your in-class examples.
After reviewing the notes and formula, do your homework with a pencil. After you finish, use a red pen to make corrections according to the solution. Please please please be honest with yourself. Do not copy the solution with a pencil. I saw many “perfect homework” (also “perfect practice exam”), but low scores on actual exams. We need to know our mistakes and weaknesses so we can improve!!! Mistakes are our teachers!!! Come to ask me if you don’t understand some solution.

How to turn in your work (quiz, practice exam, and exam correction ) on Canvas?
For each individual assignment, please take pictures of your work and combine into a SINGLE pdf, then upload to Canvas. Please make sure the pictures(pdf) are readable orientation and in good order.
Ways to convert your pictures into a SINGLE pdf:
1. Use smartphone app such as pdf scanner, Genius Scan, CamScanner
2. Copy those pictures in word/ google docs, then convert to a SINGLE pdf
3. Use some website like https://imagetopdf.com/ to combine pictures into a SINGLE pdf
Thank you! If you have any questions, please email me. Cheers!
Homework assignments:
Go to Canvas and click the corresponding homework links.
You have unlimited attempts for the homework. So you can re-do some homework questions to get a perfect score. You can attempt each problem three times and then the system will generate a new but similar question as many times as necessary.
I've included a sample homework solution below. I strongly recommend that you review class notes and then work on your homework. Please write down all the details of your solution in a notebook. If you don't get the right answer, read the solution and follow the steps to work on that question. Save your work in the notebook so you can study later to prepare for exams. Cheers!
