Contact me at williamson@tamu.edu

Please put "chem 102" in the subject line of your e-mail to me. I answer student e-mail first in my chem 102 folder and the others go into junk mail, so your messages will go to junk without chem 102 in the subject line! I only ck junk every couple of weeks or so!

PLEASE DO NOT USE @ neo.tamu.edu OR @email.tamu.edu to contact me- THESE WILL NOT GO THROUGH! Use williamson@tamu.edu if you need to contact me!

GRADES: 

**IF YOU MADE A 'D' in chem 101, you really should consider retaking chem 101 or have a very good reason for this score if you decide to continue in chem 102. Ideally, you want to have all of the concepts from chem 101 firmly understood, so you can go on to chem 102. I will always remind you of the concepts we are building on, so you can review the material if you need to. Some students will be coming from 107 or from testing out of 101.

**What are my recorded grades??? See your grades on Ecampus!

**How do I calculate my MIDTERM grade???Click here!
At midterm, we had 128 points possible (E1 = 100 pts, Homework 1-2 = 20 pts, Assignments 1-2= 8 pts) NOTE: clicker points will not be in Midterm grades, nor will anything be dropped. This is NOT midway of the 670 pts possible in the course!! MIDTERM TOTAL POINTS AND LETTER GRADES ARE POSTED ON ECAMPUS. To keep the percentages for each type of grade (Exam, homework, assignments) about the same as they will be at the end of the semester, I had to go with 128 points at midterm.

**How do I calculate my FINAL grade???
Click here for an excel file that will download to your computer. On page 1, you can enter all of your earned grades, plus estimate the future grades, while on page 2, you can enter your grades for exam 1-4, homework, clickers, assignments and it will tell you what you need on the final for each letter grade.

**Is there any extra credit?  NO EXTRA CREDIT. (This is the policy for most college-level courses.) Only the credit offered on assignments, clickers, homework, exams is available.

PAID Individual Tutoring
See me during office hours for ideas about individuals who will tutor for hire in one-to-one sessions.


PAID Group Tutoring
* *I don't really recommend any tutoring agency. I think you can pick it up yourself or with the free help available (the SI, the IA, the 406 HELD help desk, the tutor zones, my office hours, the sample exams, and reviews movies!). I think the problem with these tutoring agencies is that they teach: 1) methods other than what I do, so students get confused and remember about 1/2 of each so mess up the exams and 2) shortcuts that only work in certain circumstances, so students miss it when I give questions. Use the free tutoring if possible! See me during office hours for ideas.

HOMEWORK:

You will have 7 sets of homework assignments, worth 10 pts each. When you miss a problem your online homework will show you how to work it or give you hints about how to work it. Then you will be given a similar, but different problem on your next attempt. You will have 10 attempts to get the problems correct.

Only the graded assignments MUST be done. The others are for your study (practice). You only need to do the required number of questions (e.g., 2 of 3). No extra credit for doing 3 of 3.

No difference in credit by attempts. You get the same credit if you complete the assignments on the first try or on the 8th try. No deductions for the number of tries it takes you to get to the required number of questions. Scroll to see all assignments in MindTap when in the weekly view

For 502 AND 505 using MindTap (some call it OWLbook or the Vining book): Credit is given for the number of assignments (tutor questions and interactive questions) and mastery exercises that are mastered by the due date. Things like the Review, Challenge, and Study Guide are for your practice. I recommend these for study AFTER we have finished a chapter.

So if you master all that are assigned, you should receive full credit (10 homework points). The total possible is the addition of the numbers for all graded assignments. For each set, if you did all or at least 95% you will get 10 pts. If you get 90% of them, you will get 9 pts, 80% = 8pts, 70% = 7 pts, 60% = 6 pts, 50% = 5pt, 40% = 4 pts, below 40% = 0 pts.

Please note that there are computers in the student computing center, which you can use for homework, etc.  You will need your netID and password.

**YOU MUST USE http://www.owlv2.com/TAMU_SP17.html to buy your homework/textbook system to get the TAMU prices. This deal will ONLY be available from our TAMU link. The publisher offers a 14-day free trial that can be used until you purchase your access code. If you want to take this option, see under To Register below.

**To Purchase your textbook bundle go to http://www.owlv2.com/TAMU_SP17.html , choose 101/102, then our section. When you click on purchase next to our class, you now have the option of getting the textbook/homework/ebook in a number of formats. If you DID NOT buy a 24-month code for MindTap or OWL in your 101 class, then then you want to buy the $58 version, which does not include the print copy. You really won’t need the print book. The homework system is really embedded in the book, such that you read a short section of the book, then have questions right below it for most of the assignments….. so unlike some homework systems the text and the question are in the same screen. Again, a number of my past students didn’t really want a print book. There are also options for $100 for 24 months to cover both chem 101 and 102. The one option is without a hard-copy of the book, BUT one labelled as "epack" includes a hard-copy of the textbook, and they will mail it to you. If it is backordered, they will mail it to you when it is ready. You will get your access code for the electronic parts immediately.

**To Register: You can click on "register" next to our class from http://www.owlv2.com/TAMU_SP17.html . You will be asked for your Cengage Brain account or to set up an account. If you purchased the book from the bookstore, you will enter the access code that will be on a card inside the book. If you just purchased from the website, all you have to do is log in with your Cengage Brain account. You can also opt to set up a 14-day free trial. You could also wait until the Homework help desk opens during the first week. The TA here can help you through finding and registering your code.

You shouldn’t need a course key to register for the course if you follow this: go to : http://www.owlv2.com/TAMU_SP17.html Choose 101/102, then your section, then hit the register button. It will ask for your email and password that you gave Cengage when you purchased the code, then you will automatically be registered into the course.

**If you purchased a 24-month OWL code last semester, you can exchange it for a MindTap code by clicking 101/102 from http://www.owlv2.com/TAMU_SP17.html. Then choose 101/102 and go to the bottom where you will see a link to exchange codes. Note, this offer is ONLY good for students who bough the 24 months of access - all accounts will be checked. Please allow three business days for your request to be processed. Note you can also use this website to go from MindTap to OWL.

Use this website to login AFTER YOU ARE REGISTERED in the course: https://login.cengage.com/cb/ NOT from ecampus! Ecampus is down too often!

SYLLABUS/CALCULATORS:

Click here for the syllabus and calendar in pdf. This is also on HOWDY and was emailed to you!

Ck your syllabus for your clicker and calculator needs.

You will need acrobat reader to see and print these. If you need acrobat reader click here

**Students cannot use calculators that are programmable or have alpha-numeric capabilities for the exams. This means no TI-eighty anything. You CAN NOT use a TI-83 since it has alphabetic memory. You need a TI 30 or 36 or its Casio equilivent. The calculator cannot have alphabetic memory. It should cost $9-15. Be sure to buy one with the keystrokes you like. For example: TI-83 require that you put in log then the number. If you want this same keystroke for your lower calculator, then at the store, hit the log button. If the calculator gives you an error, this calculator will require that you put in the number, then hit log. If the calculator says log and is ready for the number, this calculator has the same keystrokes as your TI-8X.

YOUR EXAMS:

**If you think there was an error in grading your exam after you compare the score you get with grading duing the key and the grade posted on ecampus. go to 412 HELD, fill out a regrade form, and turn it in. They will make a copy of your scan, hand grade it, and tell you when you can pick up the form and copy.

**If you missed an exam and need to sign up for the makeup exam, see or e-mail me. Makeups are granted for university reasons (or VERY good ones). Otherwise, the missed exam is the one you will replace with the final percentage.

**I do not return exams. You can review your exam and rework the problems on your exam during office hours (IA's or mine). You may only visit your exam until the next exam. You can rework the problems, but NOT copy the questions down. You can only review exam 1 until we have exam 2, and so forth. You will receive any short answer part back once it is graded.

** Remember that your final percentage can replace your lowest hourly exam, but you don't want two low exams (final's are worth 165 pts, so the percentage will replace your lowest 100 pt exam). ...so 1 bad exam is not a problem, but you must do well on the remaining

*Rremember that your clicker, homework, and assignments pts should be 105 pts (15 + 70 +20) on which you should have at or near 100% on. IF you are doing these, you can make a little lower on exams than the letter grade you want in the course. For example if your exam average is around 68, then your points for clicker, homework, and assignments will bring up your course grade to a C (if you have all of these points).

**When it is available, download the grade calculator in the grades section below.

**Why is the exam average important???There is no extra credit. I don't curve, but will lower the points required for each grade at the end of the semester, based to a large part on the averages on the exams. Use the average to let you know both how you are doing compared to the class and how the class is doing. also remember that your exam grades can be a little lower than you want for the course, since your quizzes (36 pts) and homework (70 pts) are more than a test grade, for which you should get close to 100, in addition to the 1 exam grade that you can drop.

**Not happy with your Exam grade? Here are things that have helped students in the past:

**To study for the exam: 
1) do the two sample exams,
2) do some of the quizzes from the study guides on the appropriate chapters,
3) go over your objective sheet,
4) practice any objectives that you are weak on by doing more problems on that topic (using the quiz feature of the study guides for each chapter)
5) Do a quick read of the sections that are stated on your objective sheet.
6) Finally, go over the sample exams again, this time read the question and say HOW to work the problem, then uncover your answer and see if you know how to work the problem by reading it.
7) Then get a good night's sleep!!

CLICKERS/RESOURCES/GOGGLES/LAB:

**CLICKERS

You will need an iclicker2. It is easier to get this from one of the bookstores in town. Some of the bookstores have used ones. You can order it online from iclicker-see the section below. Also see the clicker section below about how to register it! You do NOT need the iclicker with reef polling, only the remote!! BUT the one with reef polling will do the plain polling we will do, and it is the university approved one that you might need throughout your time here. We will use the iclicker everyday, BUT it will be the second week or so until we begin counting it for a grade!

Register your iclickers at https://www1.iclicker.com/register-clicker/ This is also linked on Howdy. WHEN YOU REGISTER YOUR CLICKERS, USE YOUR TAMU UIN!

**Chem 102 is the lecture course.  Chem 112 is the lab course.  These are separate courses. Chem 112 will be taught by a Teaching Assistant (a TA).  Dr. Lee is the lab coordinators, in charge of TAs, curriculum, and grades.  The instructor listed on Howdy, is only the lab apparel safety inspector! If you have questions about the lab course contact Dr. Lee at edlee@tamu.edu (not the safety inspector).
