I mark complex analysis homework. Common mistakes I saw in the last set:
>Let [math]\gamma : [0,i]\to \mathbb C[/math]
>[math]\int_1^z \frac1w dw = \log z-\log 1=\log z[/math]
>[math]\frac{1}{|z^2+1|}\leq \frac{1}{|z^2|+1}[/math]

it goes on and on. These people I correct are serious brianlets

Nice damage control, physishits.
