The results of the final exam, and your final points total and your grade for the class are now posted in the "Your Points" page. Click HERE. REMEMBER TO HIT REFRESH ON THE POINTS PAGE TO MAKE SURE THAT YOU ARE SEEING THE LATEST VERSION (it is a large file, it may load slowly).
Now that the final points have been posted there is no way for you to change them, there is no extra credit, no way of changing any points for any reason, please do not ask. I have personally regraded all of the final exams for all students who were within 30 points of the grade cutoffs. There will be no further regrades. The only exceptions are if there has been a serious data entry error. If you find one then send me an email asap.
It has not escaped my attention that several of you have points totals that are close to the cutoffs, however, I have already looked at your final exams and I am very sorry, there are just no more points for you to earn. If this is you, I understand your frustration and you have my sympathy, but please remember that the majority of students who earned the higher grade scored more than 100 points more than you did.
If you want to look at your final exam then I will be in my office over the summer, but not all of the time and I can't guarantee when I will be on campus and when I won't be. University rules state that you can look at the test but you cannot take it, I have to keep it for my records for 1 year.
You will also be able to look at your final exam at the beginning of next semester.
Many of you worked extremely hard in this class and I thank you for that. I very much enjoyed teaching this class this semester, it was an honor to work with you all, especially those who started this journey all the way back in August 2017.
I hope that you all have a great summer.
The Current Points page been updated with your scores for all of the quizzes, AND, all midterms after all regrades, and your homework points. Click HERE. Please check to make sure there are no errors. Regraded midterm scores are in THIS SUMMARY ONLY, I have not gone back to the original list on the exam scores pages to update those too, take the Current Points page as the definitive list of points.
There was an error in the quiz points in the version of the points summary originally posted at around 8PM, that was fixed at 9:45PM, Saturday, so make sure you refresh the points page so that you are seeing the latest version. Any errors must be brought to my attention by the end of the day Sunday May 6th.
br> Please take a look at the scores and check for errors. Any errors must be brought to my attention by the end of the day Sunday May 6th.
br> The only additions to the points on the current points page will be the final exam
Once the final exams have been graded I will personally regrade the exams of every student who is within 30 points of one of the grades cutoffs, there will be no student requested regrades for the final, and no further regrade requests will be accepted for any earlier exam. I hope to post the final points and grades Sunday May 6th. Once I have posted these final grades they cannot be changed. If you are close to a grade cutoff and didn't make the higher grade it will not have escaped my attention, I will just not have been able to find the points on your final to get you there. Please don't ask me to reconsider your grade, I do not award grades, you earn them based on the points you received, I simply make sure that you haven't missed any points by regrading your final exam. So please don't send me emails asking me to reconsider a final grade assignment.
I am not allowed to give you your final exam, since I have to keep them for record-keeping purposes, but you are allowed to look at it. I will not have regular office hours now that the semester has ended and so I can't guarantee when I will be in my office, but you are welcome to try at any time if you only want to pick up your test. However, I won't have time to discuss your test with you. May will be extremely busy for me since I have a huge project due at the end of the month. Thanks for your consideration of these "rules".

The regraded midterm #1 and midterm #2 scores are in THIS SUMMARY ONLY, I have not gone back to the original list on the exam scores pages to update those too, take the Current Points page as the definitive list of points.
Your final grade will be determined according to the following points summation:
midterm 1 + midterm 2 + midterm 3 + final exam + quiz points (after dropping the lowest four and normalizing to a maximum of 50) + homework points (normalized to a maximum of 50 for 800 problems attempted)
The final is out of 375 points and it is cumulative, see the previous post for more information on the final exam.
To receive all of the homework points you will to have "attempted" 800 problems. which means attempting to answer or self-reporting an answer, you get equal credit for getting the problem correct or incorrect. You can see how many problems you have attempted so far by selecting the "All" option under the Questions Tab on the homework site. The deadline for completing the homework problems is the end of the day, Tuesday May 1st.
You will have noticed that there are no practice exams for the final exam on the homework site this semester, I have these practice exams in the form of a pdf file instead, links are given below.

HOW TO PREPARE FOR THE FINAL EXAM:
It used to be that my final exam was approx. 1 week after my last lecture, and then the final exam schedule changed a couple of years ago and now the final is the Monday after the last lecture. Curiously, the class didn't really do any worse on the final exam after the switch, which I think just reflects that students just switched around their study schedule. Nevertheless, the final does come up very quickly, and I think that you need to be preparing for it now, especially since we still have material to cover.
And so PLEASE try to find some time to get started on the homework for the final NOW. If you can get started early then you will have a much less stressful weekend before the final.
Material for the FINAL EXAM: The final will be roughly 50% material since the 3rd midterm and roughly 50% "greatest hits" from earlier in the semester, look at the old final exams and practice exams for guidance.
To study for the final I suggest that you focus primarily on the material since the 3rd midterm, since roughly 50% of the points will be on that material. Don't try to go back and study everything from before the 3rd midterm. Instead, Then I suggest going over the old final and practice exams and use those to guide you as to what material from earlier in the semester you need to work further on. You will find that just by using it you will have now learned a lot of what seemed difficult earlier in the semester!
If you have questions I suggest that you try asking them on the class Facebook group page, I like to answer questions there because then many people will see the answer instead of just one. More...

The quiz submit page still seems to be having problems fro some students, and so the deadline for quiz #7 will be pushed back until we find out what is happening. The new deadline will be the end of the day Tuesday Feb 27th. After 6PM today the quiz page will automatically set to the new Quiz #8, it will take until tomorrow to fix the deadline and allow Quiz #7 to be submitted until the end of the day Tuesday, and so if you can't submit the quiz try again tomorrow towards the end of the day, don't try this evening because because it will be expecting quiz #8. Don't worry, everyone will have a chance to submit quiz #7
The quiz submit system seems to be down, apologies. If it doesn't come back by tomorrow I will push bask the submit deadline for quiz #7. Thanks for your patience.

Well, this semester is starting as a comedy of errors! First we had the notes printing problem, then we were locked out of the classroom on Wednesday, and then today the projector didn't work and I had to use the Whiteboard! So I just found time to re-record todays lecture in my office, and it is now on the recorded lectures page, which is why it is late today. Again, as often happens, when I record a lecture in my office instead of in front of the class it is a bit shorter than the usual 50 minutes! More...
You will have noticed that there are some differences between your gapped notes and the ones that I have been using to recored the lectures. I have found out what happened. Every year I tweak the lecture notes a bit, not a lot, but I make a few changes to improve things. One of the changes was to move one of the example synthesis problems, example problem 4 on page 5 of your notes, to a new position after the SN2 reactions. Unfortunately, the printer printed last years version of these notes rather than the new version that I have been using. They only did this for the first section of the notes, Retrosynthesis, the rest of them for the rest of the semester are the new notes. So that is why there was a difference, specifically why that problem was in a different position in the notes. Apologies for the, but we should be OK now for the rest of the semester. More...
Well, as many of you know, the LS A0191 classroom was LOCKED this morning, which meant that I had to cancel class. I recorded the lecture in my office, and it is now posted as lecture #2 on the recorded lectures page. As often happens, when I record a lecture in my office instead of in front of the class it is a bit shorter than usual. More...
The gapped notes are now available for purchase in the ASU bookstore.
The first lecture has been posted on the recorded lectures page. More...
So there was a small typo on the syllabus I posted on here a couple of days ago, in the Schedule part (but not in the man part). The date for the 2nd midterm was given as February 13th, when in fact it will be February 12th. This typo is fixed on the syllabus that is posted on this site now, it will also be fixed on the hard copies of the syllabus I will distribute in class tomorrow.
If you did not take my first semester CHM 233 class, you may not have covered some of the radical bromination reactions that you need to know for this semester. I have a review lecture that covers these (and also elimination reactions) that you will probably find useful.
This review lecture has gapped notes, click HERE to download the notes. To watch the review lecture, click click HERE.
I also have review lectures on other topics that may not have been emphasized in your first semester class, each one has gapped notes:
Click HERE for basic principles and electron energies. The gapped notes for this review lecture, are HERE.
Click HERE for basic principles and Lewis acid/base Reactions. The gapped notes for this review lecture, are HERE.
Click HERE for Resonance. The gapped notes for this review lecture, are HERE.
Click HERE for reaction Energy/Coordinate Diagrams. The gapped notes for this review lecture, are HERE.
To see the first quiz, click HERE.
The deadline for submission of this quiz is TUESDAY, Jan 16th, this is AFTER the drop/add deadline. Because this class doesn't use Blackboard, I have to wait until after the drop/add deadline to make sure that the class roster is settled. DO NOT CLICK the SUBMIT QUIZ tab or attempt to submit this quiz UNTIL ANNOUNCED ON HERE THAT QUIZ SUBMISSION IS OPEN, which will probably be on Tuesday Jan 16th.
The class has a Facebook group page. I understand that not everybody likes to use Facebook, but this group has been quite successful in the past, Facebook allows very easy access, and when I ask the class if we should move away from Facebook the answer is always no. And so I encourage you join and to ask questions there, since everybody gets to see the answers, which therefore makes the questions useful to the entire class. Click HERE to access the group.
The syllabus is the same for both the regular/onground and the hybrid classes. To get a copy of the syllabus and class schedule, click HERE.
This class uses "gapped notes". You MUST buy a copy of these from the bookstore, they take the place of a textbook, which is not required for this class. The gapped notes will be delivered to the Bookstore on January 8th, so call ahead to make sure they are there before you go to buy them. If you go on Tuesday January 9th they will definitely be in stock. To get a copy of the first few pages of the gapped notes that should last for the first 1 - 2 lectures, click HERE
This class does NOT use a textbook. Textbooks are good for reference, but I strongly believe that they are not very good for teaching and learning. Your lecture notes should give you all of the information you need, and you can only learn organic chemistry by doing organic chemistry, not by reading it in a textbook. This class places a lot of emphasis the homework site, this is where you do organic chemistry and this is where you learn organic chemistry.
You do, however, need a copy of the Gapped Notes, see above.
Welcome to a new semester! The first class is Monday, Jan 8th. I will distribute hard copies of the syllabus and a small version of the gapped notes that should last 1 or 2 lectures. The gapped notes should be available in the ASU bookstore on Monday Jan 8th, but you might want to check before you go. They should definitely be there by Tuesday Jan 9th.
I will not go over the syllabus/policies in class on Monday, most of you will know these from the first semester class.
Instead I made a video introduction to the class, click HERE
