The primary tools needed for Test #1 were the row operations tool and the matrix tool. Some of you used a graphing calculator or some other online tool for solving linear programming problems by graphing.
For Test #2, there's no graphing to be done. You do need to be proficient with the row operations tool in order to use the simple method efficiently. Beyond that the main thing you'll be working with is calculations involving the counting techniques. Pretty much any sort of calculator is sufficient for those. So there's little need for other websites for finding tools for this test. The same tools that were available for Test #1 are still available, but there's nothing fancy that is of much use for Test #2.
