Lewis Structures on the Midterm

If we answer questions on the midterm asking to show the Lewis structure of a molecule, and answer with a drawing of the molecule with different angles from the VSEPR model (not just 90 degree angles), will we be docked points? Or is the answer okay if it is the correct VSEPR shape?

I think Dr. Lavelle mentioned that we would not have to draw any VSEPR shapes and rather the Lewis Structure would be sufficient.

You should check out previous year midterms as a good indicator of what kind of questions the midterm will be asking. Past midterms have many lewis-structure questions that asks to construct the shape of a molecule and answer some questions about its characteristics. The shape could be lewis, but vsepr knowledge would guide you to determine if it is, for example, polar or non polar. Also depends on what the question asks.
