## Main Question or Discussion Point

A recurrent problem I have when facing written examinations (I'm a math major) is calculation mistakes. They often have a devastating effect e.g. I just badly failed a quantum mechanics examination because I found the wrong eigenstates for a certain Hamiltonian which led to the rest of the questions of the test becoming trivial (vanishing expected value of energy ecc) which of course the instructor could not tolerate. The mistakes was a stupid wrong calculation of the eigenvectors of a 2 x 2 matrix. After realizing that something was wrong I looked for the error but it took me too long to find it...

It's really frustrating to perform poorly in written tests because of mistakes like these and it seemes to be happening too often lately. Has anyone here been in a similar spot sometime in his life/career? What am I doing wrong? Too little practice with exercises?

Thanks in advance
