Spend longer whenever you need.</p><p>A decision chooses which statements run. The policy here is “ready at 80 or higher.” Trace 85, 79, 80, and 81 before running each case. The comparison includes 80. A program that prints the right answer for 85 may still be wrong at the boundary. Add a separate check rejecting scores below 0 or above 100; rejection and needing practice mean different things.</p><p>Indentation groups statements. <code>def</code> defines a function and <code>return</code> supplies its result. A dictionary maps keys to values. The isolated Python 3 lab has the standard library; external packages are not installed by student code.</p><pre><code class="language-python">score = 85
