<p>2046L was definitely a huge step above 2045L. I remember people going to some website and they copied sample schemes a grad student made for the unknowns. Also watch out for TA’s that will shortchange you on your subjective grade. I think the grading scale ends up being pretty reasonable, and there are a couple unknowns that can be done for extra credit plus a non-compulsory final that can help your grade if you don’t do well.</p>
