Transition states and mechanisms?

[Pratyusha_M_1M]

Do we need to draw transition states for mechanisms?

[feodora_r_3d]

I think this depends on the question and usually the question will specify whether we should draw the transition states or not. But in most cases like the ones in the practice finals, when we are asked to draw the mechanisms, drawing transition states are mandatory ( and is stated in the question )
