While the bond angles and shape do not have to be drawn correctly (because you can tell the shape based on bonding pairs / lone pairs), it would be extremely helpful to draw them as close as possible. If the question specifically asks for the lewis structure, then it does need to be drawn correctly.
When drawing the Lewis Dot structures I think it is important to make sure you have placed the correct amount of double bonds and single bonds and lone pairs around all of the atoms; however, I don't think it is important to make sure your drawing is depicting the correct angles of the bonds because that would be very hard to do. It is just important to write the correct angles and identify the shape.
You must have the right type of bonds and number of lone pair electrons in your Lewis structure to get the right shape, and therefore, bond angles. However, because resonance is just a blend of all possible structures, you can get the right shape with just one resonance structure.

Everything that he has covered after the Midterm up until the first slide he will show us in this Monday's lecture will be on the test.
