Im not retarded, I know that other components like opamps or fet transistors would give more perrfomance, but at least check the picture and read the requirements

this is for an assignment for my analog electronics lass, and those are the requimenets the teacher said

What requirements are you missing? Looks like you got the 20x gain, Not sure if the input impedance is ~20k, but everything else looks good.
