Description
html markup
shown to student

<p>Assume a student is taking 4 classes. Each class has a number of units and a grade value.</p>
<p>Ask the user to enter the number of units and grade value for each of their classes then output their gpa
which is a weighted average of their grade values.</p>
<p>
Below is a table showing grade value that you should enter for each letter grade.</p>

<table>
<tr><th>Letter</th><th>Value</th></tr>
<tr><td>A</td><td>4.0</td></tr>
<tr><td>A-</td><td>3.7</td></tr>
<tr><td>B+</td><td>3.3</td></tr>
<tr><td>B</td><td>3.0</td></tr>
<tr><td>B-</td><td>2.7</td></tr>
<tr><td>C+</td><td>2.3</td></tr>
<tr><td>C</td><td>2.0</td></tr>
<tr><td>C-</td><td>1.7</td></tr>
<tr><td>D+</td><td>1.3</td></tr>
<tr><td>D</td><td>1.0</td></tr>
<tr><td>F</td><td>0.0</td></tr>
</table>
<p>Then output which day of the week it will be (again use <tt>1-7</tt> for Sun. through Sat.) after the <tt>n</tt> days will pass.</p>
