Welcome to Biology 1A, UC Berkeley, Summer 
2004 
 
Introduction:  Hopefully you will find Biology 1A to be a fun and exciting class.  It will be readily 
apparent to you that the lecturers, graduate students, and staff enjoy biology and teaching!  Warning - 
the pace will be blistering fast.  You are expected to have a good understanding of chemistry—examine 
the chemistry review sheet on page 6.  The class consists of four lectures, two labs and two 
discussions each week. 
All students must fil l out the form on page 7.  Use this form to add/switch AND create a 
password.  Even if you are not switching or adding you must fil l out this form – to select 
a password.  Turn it in after lecture or place it in the mailbox outside of 2088 VLSB, by 5 PM on 
June 21. 
Attendance:  You are expected to attend ALL lectures, discussions, etc. 
Communicat ion:  Office hours are held in 2084 or 2088 VLSB.  Messages for lecturers, Mike Meighan, 
and the GSI's may be left at 510-642-4110.  Email addresses are on page 4.   
Lectures and Lecturers:  The lecturers are Dr. Jim Baxter  (6/21 - 7/15) and Professor Neeraj 
Chugh (7/20 - 8/11).  Dr. Steve Takata will give one lecture on July 20.  Lectures are held M. - Th. 
from 12:30 PM to 2:00 PM in 1 Pimentel.  Lectures are not webcast.   Black lightning note-taking is 
authorized to take notes.  
Office hours:  Office hours are held in 2084 (or 2088 VLSB).  See page 4 for a list of office hours.  
Please come to any office hour—lecturer’s, GSI’s, or Mike’s. 
GSI’s:  The GSI’s will teach labs and discussion.  Each will hold one office hour per week. 
Labs and Discussion:  Labs and discussion meet twice a week and are required.  You must f il l out 
the form on page 7.  Turn it in after lecture or place it in the mailbox outside of 2088 VLSB, by 5 
PM on June 21.  Further lab information is provided.  Mike Meighan will handle section changes and 
adding. 
Repeating Students:  Students repeating the class may not have to repeat the lab if they scored 
above the lab mean (when they took the class).  If interested, fill out the form outside of 2088 VLSB 
by 5 PM today.  Eligible students will be contacted (by phone/email). 
Study Advice:  Read the material before lecture!  At a minimum read the first page and last two 
pages of assigned chapters.  During lecture take notes and pay attention.  Refer to the lab manual for 
further information on studying.  The Student Learning Center will be offering study groups on M/W 
from 10 AM to Noon and  on T/Th 9-11 AM.  There will also be drop in hours. 
GRADING PROCEDURE:  Letter grades will be determined from numerical scores as follows: 
Midterm Examinations (2 x 150) (each lecture is worth about 15 points) 300 pt’s 
Laboratory & Discussion:  
     Lab Exam # 1, 7/26, in lecture (Labs 1-7)  90 pt’s 
     Lab Exam # 2, 8/9 or 10, during your lab period (Labs 8-12)  75 pt’s 
     Quizzes - In discussion or lab (12 labs x 3 pts minus the lowest quiz scores) 33 pt’s 
Final Exam (held on 8/12) 105 pt's 
Total 603 pt’s 
 
A+ or A or A- 100-90% C+ or C or C- 79-70% F 59-00% 
B+ or B or B- 89-80% D+ or D or D- 69-60%

Grades are typically curved.  Minimum grades as l isted above are guaranteed.  The total 
% needed for some form of an A, B, C, or D may be lowered depending upon the f inal  
distribution of students scores, i.e. we curve the class if need be.   
GRADING PROCEDURE: 
In the event that some examinations have been unusually difficult, the cut-offs for letter grades 
may be lowered (but only by a few percentage points, and only as deemed necessary).  Historically 
around 50% of the class EARN A’s and B’s.  Grades are based upon total points which includes your lab 
and lecture points.  Some adjustments are made to lab exam 2 grades and quiz grades to adjust for 
differences between the various sections.  How is this done equitably? 
A linear regression analysis is used to adjust grades.  The mean for lab exam 1 is determined for 
each section and those values are used for the X axis.  The mean of lab exam 2 (or quiz scores) are the 
values used for the Y axis.  A best fit line is generated.  Each section is then adjusted UP to the 
“easiest/highest” of all of the sections (maintaining the same slope but modifying the intercept which 
adjusts for the “easiest/highest” section).   Then adjustment points are added for each student within 
a section.  Thus no students are penalized (for being in a “hard” section) and no students have an 
advantage (for being in a “easy” section).  See below for a graphical representation of these 
adjustments.

Average lab exam 1 scores, quiz scores, and lab exam 2 scores are determined for each
section/pairing (2 sections take the same lab exam 2).  Lab exam 1 averages are used for the
X axis and quiz scores (or lab exam 2) for the Y axis.  A best fit line is generated.  The slope
of this line is kept and is brought UP TO THE :EASIEST/HIGHEST" average.  This is
repeated for lab exam 2 (Y axis).

The total points is then determined for each student.  We look at 90% of the points in the class 
and see what % of the students earned a guaranteed A+/A/A-.  If there are fewer than about 20% of 
the students we then typically lower the number of points required for some form of an A (since it is 
the lower end it would be A-).  We continue to do that for each guaranteed grade range, B, C and D.  If 
need be, we lower the total number of points necessary to get a certain grade.  We usually give out 
about 20% A’s, 30% B’s, 20% C’s, 10% D’s and 10% F’s.   We then go back and make the exact cut-
offs for each form of a grade (eg. C+, C, C-).  We then look to see if students are within 5 points of the 
next highest grade.  If so we need to determine if they should be “bumped” to the next higher grade.  
The most important criteria for this “bump” in the summer is attendance and participation in 
lecture/lab/discussion (pre-labs/worksheet averages).  We only consider bumps if the students are 
within 5 points.  On average about 50% of the students who are within 5 points get bumped, 50% do 
not. 
Note that the class is, in a sense, curved.  But we would rather that you strive to reach the 90 
percentile, instead of us having to lower the percentage cutoffs for given grades.

Lecture:  Lecture exams will be taken in class.  The midterms are scheduled for July 12 (lectures 1-
10 or 11 = 150 pts,) and Aug. 2 (lectures 11 (10) -14 = about 60 pts, lectures 15-20 = about 90 
pts).  The final is scheduled for August 12 (lectures 21-27, 105 points). 
 
 
Exam Format:  Exams will contain both multiple-choice questions and short answer, essay or fill in the 
blank questions.  150 point exams will have about 100 points multiple choice and 50 points that will be 
short answer, essay or fill in the blank.  The final will be 85 points multiple choice and 35 points short 
answer, essay or fill in the blank.  Lab exam 1 will have about 35 pts multiple choice and 55 pts short 
answer.  Lab exam 2 will be almost exclusively short answer. 
There will be NO make-up exams.  If you miss an exam due to illness, you must present a written, 
verifiable medical excuse.  Your exam will be calculated on a pro-rated score.  
 
 
Lab:   Daily lab quizzes worth a total of 33 pts (12 X 3 pts minus the lowest score) will be given at the 
start of each lab.  Pre-labs are required in order to do lab.  Worksheets are also required.  Lab exam 1 
worth 90 points will be held in lecture on July 26.  It will cover labs 1-7.  Lab exam 2, worth 75 pts, 
covers labs 8 – 12 and will be given in your lab, either Aug. 9 or 10th.

1.  All students must fill out this form. 
2.  Labs and discussions begin on Wednesday and Thursday.   You are enrolled in the Lab and 
Discussion assignments as assigned by Tele-BEARS (Summer Sessions).  Only a limited 
number of section changes can be made (don't assume you will be switched- if there isn't 
space there isn't space). 
3.  To add or switch sections fill out this form completely and turn it in after lecture.  Select 
from the four choices, A, B, C or D.  (See below.)  You cannot mix lab/discussion times.   
4.  Order the choices in your order of preference.  You most likely will not get your first choice. 
Please indicate your choices in the lower part and turn this in after lecture.  Turn in only 
the lower part.  Keep the upper half. 
5.  Section changes and Adds will be posted in the glass case outside of 2084 VLSB on Tuesday 
at 11 AM.  All changes are final.  There will be no section changes thereafter. 
6.  You must attend your assigned lab and discussion section starting Wed. and Thursday.
