<h3><strong>Checking and Submitting and Answer</strong></h3>
<p style="font-size: 16px;">For each problem, you will have three attempts to submit an answer, with the exception of problems where an attempt reveals the answer (e.g., True/False questions), for which you will be limited to a single attempt.</p>
<p style="font-size: 16px;">To submit your answer, click the "Submit" button. This will automatically submit the problem for grading purposes, and the edX platform is able to verify your answer and give you immediate feedback as to whether or not your answer is correct.</p>
<p style="font-size: 16px;">The number of attempts allowed as well as the number of attempts you've already made will always be visible on a problem's page at the bottom, next to the "Submit" button. Please note that for problems consisting of multiple parts, hitting the button will count as an attempt for all parts of the problem. Unfortunately, it is not possible to submit answers for one part at a time.</p>
<p style="font-size: 16px;">A "Show Answer" button will appear after the due date of the problem set. Clicking this button will reveal the correct answers and solutions.</p>
<p style="font-size: 16px;">You are strongly encouraged to look at the solutions even if your answer is correct.</p>

<h3><strong>Answer Formats</strong></h3>
<p>This course will use two answer formats:</p>
<ul class="itemize">
<li>
<p>Numerical answers: Enter a number, either in decimal (e.g., '3.14') or fractional form (e.g., '22/7'). Do not enter any non-numerical letters or symbols. To account for rounding, the system will accept a range of answers as correct. Unless otherwise specified in the problem, your answer should be accurate to 2 decimal places. If a question asks for a number in percentage form, type only the number (e.g., enter '5.42%' as '5.42'). Do not use commas when entering numbers.</p>
</li>
<li>
<p>Multiple choice: Select the correct option from the drop down menu or radio buttons.</p>
</li>
</ul>

<h3><strong>Discussion forum overview</strong></h3>
<p><strong>(For informational purposes only - discussion forums are not active on the MIT Open Learning Library.)</strong></p>
<p style="font-size: 16px;">The course provides an online discussion forum for you to communicate with the course team and other students. You may access the forum through the "Discussion" tab at the top of the page, as well as through many embedded discussions within each unit. We recommend using the embedded discussions within each unit to discuss topics related to a specific unit's materials, whether it's lectures, solved practice problems, or problem set problems. Please see the guidelines below for more information on how to use these embedded discussions.</p>
<p style="font-size: 16px;">For other more general discussions, you may use the "Discussion" tab at the top of the page. When creating a new post, <b class="bf">please choose one of the following categories that best describes your post</b>:</p>
<ul class="itemize">
<li>
<p><b class="bf">Introductions:</b> introduce yourself to your fellow students and find out more about them!</p>
</li>
<li>
<p><b class="bf">Course Feedback:</b> let the course team know how you are finding the course, what you think works well, and what you would like to see improved</p>
</li>
<li>
<p><b class="bf">Technical Problems:</b> let the course team know about any technical issues you are dealing with (e.g., playing videos, entering answers, etc.)</p>
</li>
<li>
<p><b class="bf">General:</b> other general discussions</p>
</li>
</ul>
<h3><strong>Discussion forum guidelines</strong></h3>
<p style="font-size: 16px;">The discussion forum is the main way for you to communicate with the course team and other students. We hope it contributes to a sense of community and serves as a useful resource for your learning. Here are some guidelines to help you successfully navigate and interact on the forum:</p>
<ul class="itemize">
<li>
<p><b class="bf">Use discussion while working through the material.</b> Beginning with Unit 0, each lecture will contain an embedded discussion located at the bottom of the each video clip in that lecture sequence, where you should discuss anything related to that video clip. Click "Show Discussion" to see all discussions associated with the lecture, and click "New Post" to post a new topic. In addition, every solved practice problem and problem set problem will have its own embedded discussion located at the bottom of their respective pages. As with the lecture discussions, click "Show Discussion" and "New Post" to see and create discussion topics related to that specific problem. We recommend that you use these in-page discussion boards to help focus discussions on specific topics.</p>
</li>
<li>
<p><b class="bf">Use informative topic titles and tags.</b> To make it easier to identify relevant discussion topics, please use informative titles and tags when creating a new discussion topic. </p>
</li>
<li>
<p><b class="bf">Be very specific.</b> Provide as much information as possible about what you need help for: Which part of what problem or video? Why do you not understand the question? Do you need help understanding a particular concept? What have you tried doing so far? Use a descriptive title to your post. This will attract the attention of other students having the same issue.</p>
</li>
<li>
<p><b class="bf">Observe the honor code.</b> We encourage collaboration and help, but please do not ask for nor post problem solutions.</p>
</li>
<li>
<p><b class="bf">Upvote good posts.</b> This applies to questions and answers. Click on the green plus button so that good posts can be found more easily.</p>
</li>
<li>
<p><b class="bf">Search before asking.</b> The forum can become hard to use if there are too many threads, and good discussions happen when people participate in the same thread. Before asking a question, use the search feature by clicking on the magnifying glass on the left-hand side.</p>
</li>
<li>
<p><b class="bf">Write clearly.</b> We know that English is a second language for many of you but correct grammar will help others to respond. Avoid ALL CAPS, abbrv of wrds (abbreviating words), and excessive punctuation!!!!</p>
</li>

<h3><strong>Collaboration guidelines</strong></h3>
<p style="font-size: 16px;">We encourage you to interact with your fellow students and engage in active discussion about the course. We suggest that you use the guidelines below for acceptable collaboration.</p>
<p style="font-size: 16px;">The staff will be proactive in removing posts and replies in the discussion forum that have stepped over the line.</p>
<ul class="itemize">
<li>
<p>Given a problem, it is OK to discuss the general approach to solving the problem.</p>
</li>
<li>
<p>You can work jointly to come up with the general steps for the solution.</p>
</li>
<li>
<p>It is OK to get a hint, or several hints for that matter, if you get stuck while solving a problem.</p>
</li>
<li>
<p>You should work out the details of the solution yourself.</p>
</li>
<li>
<p>It is not OK to take someone else's solution and simply copy the answers from their solution into your checkboxes.</p>
</li>
<li>
<p>It is not OK to take someone else's formula and plug in your own numbers to get the final answer.</p>
</li>
<li>
<p>It is not OK to post answers to homework problems before the submission deadline.</p>
</li>
<li>
<p>It is not OK to look at a full step-by-step solution to a problem before the submission deadline.</p>
</li>
<li>
<p>It is OK to have someone show you a few steps of a solution where you have been stuck for a while provided you have attempted to solve it yourself without success.</p>
</li>
<li>
<p>After you have collaborated with others in generating a correct solution, a good test to see if you were engaged in acceptable collaboration is to make sure that you are able to do the problem on your own.</p>
</li>
