Suggestions for success

  • Read the chapter before the lecture so you have a better understanding of the concepts.
  • As you read the chapter, try each book’s example problem. You should be able to solve the example before going on to the next problem.
  • Go through your lecture notes.
  • Join a study group and work on the problems.

PREREQUISITE:Physics 4A

FINAL EXAM: Please note that the date and time for the final exam is:

ThursdayDecember14th, 10:30-1:00p.m.

ALL STUDENTS MUST ATTEND THIS EXAMINATION AT THIS TIME.

Graphing Calculators are not allowed during any of the exams.
HOMEWORK:

Generally, homework will be assigned each class, and must be completed before thestartof the following week. The homework is normally online butcould be discussed by all students in class.It is VITAL that you attempt the problems yourself. Homework and examples in class are the basics of quizzes which make overall 10% of your grade.

EXAMS/QUIZZES:

There will be short quizzes during the semester.

The dates for exams are:

Midterm #1: Thursday September 21st

Midterm #2: ThursdayOctober26th

Midterm #3: Tuesday November21st

Final exam: Thursday December 14th

Grading:

Attention:The Final exam is cumulative.

Your grade in Engineering 40 will be approximately determined as follows:

10% - quizzes

10% - Homework

60% - midterm exams

20% - Final exam

Failure to attend the final results in an F. According to the total point score, your letter grade for the course will be determined using the scale below. There is no “curve” for this course.

Percentage of total points you obtain / Your course grade
90% or greater / A
80% or greater / B
70% or greater / C
60% or greater / D
Less than 60% / F

NOTE: If you wish to drop the class, for whatever reason, it is YOUR responsibility to ensure that the appropriate paperwork is completed and submitted in a timely fashion.
