Can you please check my work? thanks

You seem to be confusing velocities in the x and y direction. I would recommend carefully redoing your working from part 2 onwards with careful attention to splitting motion and acceleration into two components - x horizontal across page and y vertical up and down the page.

 

From a quick reading you seem to be mixing the horizontal velocity v_x 8e6 m/s due to the plates marked D with the vertical acceleration a_y caused by the E-field marked E. v_y =0 when the electron enters the E-field marked E.

 

What happens after the electron leaves the field (or gets to a point where we can ignore it)?

Why would it keep on curving as it seems to do in your diagram - remember Newtons first law
