### Study Halls

We’re testing out something new this semester - having some walk-in study halls run by our lead TA for the course. These are optional, but consider them an excellent opportunity to practice material we’ve recently covered. They will be held on:
Thursday 4-5:30pm, Hylan 1106B
Friday 3:30-5pm, Hylan 1106B
Most weeks we’ll endeavor to have worksheets for study halls. Here are the sheets from previous weeks:
Predicate Logic
Proofs

### Textbook

Discrete Mathematics and its Applications (8th edition) by Kenneth H. Rosen (Note you are welcome to use the 7th edition as well)

### Topics Covered

We will cover much of chapters 1-6, 8, 10 of the text. Among the topics we will study are set theory, formal logic, algorithms and their complexity, elementary number theory, induction, counting, and graph theory. See course schedule for details.

There will be two midterm exams and a final exam at the following times:

First Midterm - Solutions
Date: Tuesday Feb 20, 8am-9:20am
Covers: Sections 1.1-1.8, 2.1-2.2.
• Location: HOYT AUD. HOYT 104
Practice Exams:
Practice Exam A Solutions
Practice Exam B Solutions Please note that the last problem uses a symbol we haven’t defined in class yet - that will not be on your exam. The | symbol present there means “is a factor of”. With that information, the proof is feasible.
Practice Exam C Solutions
Second Midterm
Date: Thursday Mar 28, 8am-9:20am
Covers: Sections 2.3, 3.1-3.2, 4.1-4.6 and 5.1-5.4 inclusive.
• Location: HOYT AUD. HOYT 104
Final Exam
Date: TBD
Part A covers sections 1.1-1.8, 2.1-2.3, 3.1-3.3, 4.1-4.6, 5.1-5.2 inclusive.
Part B covers sections 5.3, 6.1-6.4, 8.1-8.2 and 10.1-10.4 inclusive.
• Location: TBD

• Homework assignments – 30%
• Two Midterm Exams – 20% each
• Final Exam – 30%

The Final Exam will have two parts: Part A will cover the material tested in both Midterms 1 & 2, while Part B will only contain questions related to material appearing after Midterm 2. Each part makes up roughly 50% of the final exam. In addition, your score on Part A of the final will replace your lowest midterm score if it is indeed higher than it (it can be used to replace only one midterm score, not both).

Makeup exams will only be given in extenuating, unavoidable, or extreme circumstances. If you otherwise miss a midterm exam for any reason, then Part A of the final exam will count as your makeup. Final Part A can only replace one midterm score, however.

You will NOT be permitted calculators or other electronic devices (iPhone, smart watches, etc) on any exams. You will NOT be permitted books, notes, or cheat sheets’’ on any exams.

Incomplete “I” grades are almost never given. The only justification is a documented serious medical problem or a genuine personal/family emergency. Falling behind in this course or problems with workload on other courses are not acceptable reasons.

### Attendance

Lecture attendance is not mandatory in MTH150 but is highly suggested.

You are welcome to attend any lecture (see top of webpage for the listing of times and places of the 2 different instructor’s lectures). Note that all sections of the course cover the material needed for the exams at about the same pace.

If you do attend a lecture in a section different than the one you are signed up for, please do relinquish your seat to students actually enrolled in that section if the classroom fills - in that case, usually there is room to sit in the aisle or stand at the back of class. This packed classroom situation is generally rare so it should not be a big issue, and hopefully won’t occur at all.

### Homework

There will be 10-12 weekly assignments for the semester consisting of a written portion and a WeBWorK portion. Both portions are due on Thursdays at 11:59pm. Written homework is submitted through Gradescope. Each assignment will be out of 40 total points; the weighting of each WeBWorK vs. written portion will be indicated each week. Your lowest homework score will be dropped. For due dates and times of WeBWork assignments please log-on WeBWorK to see when the set closes. Late assignments are generally not accepted, except in rare cases (such as genuine illness or emergency) supported by documentation.

A “WeBWorK TA” will be available to answer email questions about Webwork homework sets until 7pm on the due date. Questions received after 7pm may not be answered. There is a button on each problem to email the WeBWorK TA. You may access Webwork through the Course Materials menu on your Blackboard page for MTH150.

TAs and Instructors can access webwork HERE. Students should use the link on Blackboard instead.

Written assignments will be posted on the homework schedule and Gradescope and WeBWork assignments will open at least one week before the due date. You must abide by the Homework Rules (See Below)

## Homework Rules

While you are encouraged to work together on both the webwork and written work in the course, it is important that this work be internalized. To facilitate this it is a homework rule that after discussing a written homework problem with friends, TAs or instructors, you should make sure you have internalized it BEFORE writing up your final solution on your own, without reference to the helping source. Under no circumstance should you blindly copy a friend’s solution as your own work. Instead you should absorb the ideas through discussions and then reproduce solutions on your own.

If you worked together with friends X, Y and Z on written work, you should write “worked with X, Y and Z” next to your name on your homework.

Similarly for webwork problems, you should be able to enter the final set of answers on your own and be able to reproduce the solutions to the problem on your own if confronted with the problem again without any solutions.

This course follows the College credit hour policy for four-credit courses. This course meets 3 academic hours per week. Students may also be expected to deepen their understanding of the course material through close examination/evaluation of the readings assigned in the course.

### Help

If you are having difficulty seek help immediately - do not wait until it is too late to recover from falling behind. There are several avenues for you to get help and ask questions, outside of lecture:

### Disability Support

If you have an academic need related to a disability, arrangements can be made to accommodate most needs. In the event you encounter any barrier(s) to full participation in this course due to the impact of a disability, please contact the Office of Disability Resources. The access coordinators in the Office of Disability Resources can meet with you to discuss the barriers you are experiencing and explain the eligibility process for establishing academic accommodations. You can reach the Office of Disability Resources at: disability@rochester.edu; (585)275-9049; 1-154 Dewey Hall. To be granted alternate testing accommodations, such as extra time, you (the student) must fill out forms with the office of disability resources at least seven days before each and every exam. These forms are not sent automatically. Instructors are not responsible for requesting alternative testing accommodations for you, and they are not obligated to make any accommodations on their own.
