PHY 2048 Sakai eLearning WEBsite.
Your Exam Points (max = 75) assumes that you get the average of your Exam 1 and Exam 2 grade on the Final Exam.

assumes that you get the same average on all your remaining quizzes that you have for the first 7 quizzes.
Your QxHW Points (max = 10 points) include the first 7 online homework assignments together with the first 7 quizzes
and assumes you get the same average on all your remaining QxHW scores. Your HITT Bonus points (max = 5 points)
are based on your HITT scores through 3/20/15 and assumes that you get the same average on all the remaining HITT questions.
Your Total Points (max = 100 points) are the sum of your Quiz Points, your QxHW Points,
your Exam Points, and your HITT Bonus points. If you have greater than 100 points, you were given
the maximum of 100 points. The grades are calculated according to the
grade formula.

from your Exam 1 (changed slightly but same concept) and 4 problems from your Exam 2

but if you understand how to do your Exam 1 and Exam 2 problems you will be able to do these problems.

Exam 2 Grades: The grades for Exam 2 have been posted on the
PHY 2048 Sakai eLearning WEBsite.
The initial average was 9.3 out of 20 with a high score of 18. We did not intend for the average score to be this low.
Therefore, the scores have been "renormalized" by adding 4 points to everyone's score. If your initial score was 16 or higher your
new "renormalized" score is a perfect 20. The new average is 13.3 out of 20 with 22 students receiving a perfect score of 20.
The "renormalized" scores appear on the Sakai eLearning website. Congratulations to those who did well! The new estimated course grades will be availible in a few days.

"Bug" in HW5 Problem 8: There is a "bug" in WileyPLUS HW5 (Chapter 9, Problem 37). For some students
WileyPLUS did not calculate Part C correctly. Everyone will get full credit for this problem.

2.19.15 
WileyPLUS Problem Tolerance: WileyPLUS has changed the way they assign the tolerance
to the online homework problems. The tolerance determines how accurate you must calculate the
answer in order to get it marked correct. If the problem does not state the tolerance, then it
is set to 2%. Namely, your answer must be within 2% of the exact answer. If the problem states
the tolenence, for example, “the tolerance is +/1 in the 3rd significant digit”, then you must
get the answer correct to within the stated tolerance (it might be less that 2%!).
We suggest that you calculate at least up to 4 significant digits in
all your answers.

2.14.15 
Exam 1 Incident in WM 100: If you took Exam 1 in WM 100 (UZ) and feel your grade on
the exam was affected negatively by the medical emergency that occurred, you can take the
cumulative makeup exam on April 22 and we will count it as your Exam 1. However, you can
not take the higher score. If you decide to take the makeup exam it will replace your
Exam 1 regardless of whether the score is higher or lower. Please send Email
to phy2048@phys.ufl.edu if you decide
to take the makeup exam.

2.14.15 
Estimated Course Grades: The estimated course grades (after one exam) are up on the
PHY 2048 Sakai eLearning WEBsite.
Your Exam Points (max = 75) assumes that you get the same grade on Exam 2 and
the Final Exam that you received on Exam 1. Your Quiz Points (max = 15 points) include the first 3 quizzes and
assumes that you get the same average on all your remaining quizzes that you have for the first 3 quizzes.
Your QxHW Points (max = 10 points) include the first 3 online homework assignments together with the first 3 quizzes
and assumes you get the same average on all your remaining QxHW scores. Your HITT Bonus points (max = 5 points)
are based on your HITT scores through 2/9/15 and assumes that you get the same average on all the remaining HITT questions.
Your Total Points (max = 100 points) are the sum of your Quiz Points, your QxHW Points,
your Exam Points, and your HITT Bonus points. If you have greater than 100 points, you were given
the maximum of 100 points. The grades are calculated according to the
grade formula.
Your overall Rank in the class and your raw HITT, HW, and Quiz scores are also shown.
If you see a mistake please send Email to phy2048@phys.ufl.edu.
Remember this is only an estimate, if your performance level changes your grade will change accordingly!
If you did not take Exam 1 then you temporarily received a zero for Exam 1.
The zero will be replaced by your score on the cumulative makeup exam. Hence, your estimated course grade is not accurate at this time.
When you take Exam 2 your estimated course grade will become more accurate.

Normalization of the Quiz Scores: At the end of the semester we will compute the overall average quiz score for each of the PHY2048 TA's.
We will make no change to the quiz grades for those students in the classes of the TA with the highest average. We will add "bonus" quiz points to all
the other students in such a way as to make all the averages the same as the TA with the highest average. However, if doing so gives you
more than 15 points for your overall quiz grade, then you will only get the full 15 points. At the end of the semester after the quiz grades
are normalized we will recalculate the QuizxHomework scores. However, if doing so gives you more than 10 points for your overall QxHW grade,
then you will only get the full 10 points.

1.1.15 
HITT Practice Question on Monday January 12: On Monday January 12 you will be given an HITT
practice question that will help you to become familiar with the system before the
questions start counting for bonus points. The HITT questions will begin counting toward your bonus points on
Wednesday January 14.
Remember, you must register your HITT remote
here.
