<p>I've spent untold hours on the UT site and still can't find the answer so perhaps someone here can help. What do the letters at the end of course numbers mean and what does it mean if there is no ending letter? For example the core classes for History are:</p>
<p>History 314K, 315K, 315L, 317L, 320L, 320P, 320R, 329K, 333L, 333M, 334L, 334M, 336L, 340S, 341N, 345J, 345L, 345M, 351N, 351P, 355F, 355M, 355N, 355P, 355S, 356G, 356K, 356N, 356P, 356R, 357C, 357D, 357F, 357P, 365G, 366R, 366S, 376F...</p>
<p>The first number would be the credit hours.</p>
<p>The middle two numbers indicate lower and upper levels.</p>
<p>But what about the letters k, l, c, f, p, r, s, j, d, etc.?</p>
