11E7 Enrollment

Course enrollment is limited by the total number of students that can attend the laboratory sections and the room capacity in the lecture and discussion halls Maximum: 340 students

To register in E7 you must be enrolled in:a lecture, a discussion and a lab section

In previous years, most students that wanted to take E7 were eventually enrolled.

We will do our best effort to accommodate as many students as possible this semester as well.

E7 L2

12Laboratory computer usage policy

Laboratory sections can only accommodate as many students as available workstations (34).

During the time that a laboratory section is taking place, the students that are enrolled in that section have priority use of the computers.

If you want to change sections, you have to drop your current section, and then enroll in the section you want (or get into the waiting list).

Instructors cannot change wait list order or get students into a section that is full.

4E7 Minimum Prerequisites

1) Pre-calculus MATH, MATH 1A

2) MATH 1B must be taken concurrently

Posted Thursdays afternoons


NEXT FRIDAY, DURING DISCUSSION SESSIONS:

We will explain how laboratory assignments must be prepared, auto-graded and turned in.

E7 L1


Posted Thursdays afternoons


Work individually and with the GSI during the lab sections to complete lab.

DO NOT COPY CODE (we will probably catch you)

It is ok to discuss with fellow students, but not to copy code or allow your code to be copied.

E7 L1

24E7 Honor Code

The student community at UC Berkeley has adopted the following Honor Code:

"As a member of the UC Berkeley community, I act with honesty, integrity, and respect for others."

Your E7 instructors join you in pledging to adhere to this code.

7E7 Online Quizzes

We will often require students to take 1 or 2 on-line quizzes per week (one after each lecture). Quizzes will be available in the E7 bCourses

website

You can take each quiz as often as you want from the moment that they are made available, until the moment that they are closed MONDAY

MORNING (08:00 am).

We expect students to get 100% on the quizzes. Quizzes will be worth 5% of your overall grade.
