Works great, easy to use, and has all the functions you need for a finance class. I wasn't thrilled to buy a $30 calculator especially because you can use your phone or just a regular scientific calculator. BUT at least it did make some functions a lot easier (and if you're like me, you like to derive the formulas yourself), and you could use the calculator to double-check yourself. Yes, once you get into the real world you end up using a computer to generate all your tables and reports, but it is useful for doing basic work (plus has exponent and log functions that are useful outside of finance).
