<p>Did you noticed that recently multiple homework questions are posted? Just a few examples:</p>

<ul>
<li><a href="https://stats.stackexchange.com/questions/138093/question-in-following-pictures">https://stats.stackexchange.com/questions/138093/question-in-following-pictures</a></li>
<li><a href="https://stats.stackexchange.com/questions/138091/question-in-following-picture">https://stats.stackexchange.com/questions/138091/question-in-following-picture</a></li>
<li><a href="https://stats.stackexchange.com/questions/137860/tough-probability-question">https://stats.stackexchange.com/questions/137860/tough-probability-question</a></li>
<li><a href="https://stats.stackexchange.com/questions/135456/question-on-a-probability-question">Question on a probability question</a></li>
<li><a href="https://stats.stackexchange.com/questions/135975/could-someone-help-me-check-my-answer-on-this-probability-question">Could someone help me check my answer on this probability question?</a></li>
</ul>

<p>As one of the comments suggested at least two of those could have been actually posted during an ongoing exam!</p>

<p>Any ideas what could be done?</p>
