Confusing with 'occurring' as a noun., Omitting 'of' when saying 'the occurrence you mentioned'., Using 'occurrence' without context (it needs to relate to something).	Confused with 'rate' vs 'rate of' - 'rate of' implies a measurement over time., Using 'rated' when 'rate' is required - 'I rate this movie' not 'I rated this movie for now.', Mixing up with 'ratio' - 'rate' refers to the value assessment.
