In addition to office hours, please feel free to contact me via email if you are "stuck". Also, Grossmont offers some great resources to help you do well:

Math Study Center - tutors can help you with the calculation aspects of homework assignments (bring your textbook and Masteringastronomy.com login information with you).
English Reading and English Writing Center - useful if English is not your native language, especially since Astronomy has so many new words and new definitions for "common English" words.
Grossmont College Library. Copies of the textbook and lecture tutorial book will be placed in the reserve collection.
Tech Mall - computer access for all Grossmont students, and a great place to complete your online assignments on masteringastronomy.com. Bring this syllabus with you if you need help registering online and joining the online class with the "Course ID" given above.
Disabled Student Programs and Services in Room 110 (619-644-7112 voice or 619-644-7119 TTY)- specialized services including an Assistive Technology Center. Students who need accommodations for their disabilities are encouraged to contact the instructor and DSPS as early in the semester as possible so that reasonable accommodations can be implemented.
Supervised Tutoring Referral. Students are referred to enroll in the following supervised tutoring courses if the service indicated will assist them in achieving or reinforcing the learning objectives of this course: IDS 198, Supervised Tutoring to receive tutoring in general computer applications in the Tech Mall; English 198W, Supervised Tutoring for assistance in the English Writing Center (Room 70-119); and/or IDS 198T, Supervised Tutoring to receive one-on-one tutoring in academic subjects in the Tutoring Center (Room 70-229, 644-7387). To add any of these courses, students may obtain Add Codes at the Information/Registration Desk in the Tech Mall. All Supervised Tutoring courses are non-credit/non-fee. However, when a student registers for a supervised tutoring course, and has no other classes, the student will be charged the usual health fee.
