PAID Group Tutoring
**I don't really recommend any group 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 hubs, office hours, the sample exams, and reviews movies!). I think the problem with these group 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; but if you insist on group tutoring see me, as some a MUCH better than others!

**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 requires 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.
**For each exam, you will receive 2 sample exams, Brooke will do a review for each exam that will focus on the 2nd sample exam in 100 HELD:For Exam 3 (4/7), her review session will be Sunday. For Exam 4 (4/23), her review session will be. For the Final Exam (4/30 and 5/5), her review session will be Tuesday, 4/28, from 5:30-7:30pm.
**To
study for the exam,:
1) do your homework (at least some of each required section),
2) do the two sample exams- have the solution written out on another sheet of paper
3) go over your objective sheet,
4) practice any objectives that you are weak on by doing more problems on that
topic (look at the chapter reviews that will be for practice, and 'due' on the exam date. Do problems in the review for this objective.)
5) Do a quick read
of the sections/chapter 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!!
**If you want to see your exams, come in 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. I do not return exams. 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.
** 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.
**If you didn't like your exam 1 score, remember that your final percentage can replace your lowest hourly exam, but you don't want a second low exam, so: (1) Download the grade calculator in the grades section below. and (2) Review your exam during any office hour before exam 2 to decide on a personal strategy for improvement. Also remember that your clicker, homework, and assignments pts should be points 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.
**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 other activities (assignments, clickers, essay, and homework) are more than a test grade, since these total more than 100 points. You should get close to 100% on these, in addition there is 1 exam grade that you can replace with the percentage on your final.
CLASS AVERAGES for:
Exam I = Class Average = 70.1 / 100 pts for the total exam for both classes. (click here for the 9:35 key) This key is correct,but #16 Blue partial credit was supposed to be given 3 points, but was incorrectly given 2.5 pts. This has been corrected on ecampus with the new grades followed by the word 'update' for the 16 students involved.) AND (click here for the 12:45 key). Congrats to the 16 perfect scores and 45 others with 90% or better ---so 61 A's, 90 B's, 120 C's, 60 D's

**CLICKERS
The university approved non-REEF iclicker2 is ISBN- 9781429280471 (classic clicker). It costs around 56.00 new or $45.90 used, plus tax for the device. Both have no cost to register your clicker into a course. If you buy a used iclicker the company will charge you $6.99 to get that serial number linked to your ID number. We won’t use the reef polling, but you might need that for other classes. BUT the one with reef polling will do the plain polling we will do. Once you buy the clicker, you can use it for all your courses that require i>clickers for the remainder of your time at Texas A&M. You can also resell it. There are options to rent, but if you would have to rent both semesters for chem 119 and 120, it is cheaper to buy then resell later. You can purchase your iclicker2 at the Texas A&M Bookstore and other bookstores, 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://www.iclicker.com/remote-registration-form-for-classic This is also linked on ecampus. WHEN YOU REGISTER YOUR CLICKERS, USE YOUR TAMU UIN, no dashes or spaces! We will use iclicker classic, and TAMU uses blackboard for its learning management system. AFTER THE 6TH WEEK IF YOU GET A NEW CLICKER, YOU NEED TO CONTACT ME AND SEND ME YOUR NEW CLICKER SERIAL NUMBER. .
Your clicker grades are 1 pt for each correct answer up to 3 questions + 1 for responding, which you will receive if ALL questions are wrong. This means that if there is 1 question during the lecture, it will be a 2 pt day. If there are 3 questions, it will be a 4 pt day. If there are 4 questions, it will be a 4 pt day because I will take your best 3 questions +1. Clicker pts do NOT equal course points. If you get 70% of the clicker pts, then you will get all 16 course pts, if you get 65 to 69% then you get 15, etc. as spelled out in the syllabus. The threshold is low to allow for bad batteries, university absences,dentist appts, etc. and since I have just lectured on a topic, I would expect a low C. Therefore a low C or 70% is all you need for full course credit.
