That sounds like a good plan.

My loved school, and my introduction to OO was there, too.

It went something like "Learn C and get comfortable with it." and then
"Here are objects, love them!". It was a bit jarring, at least for me,
as there wasn't much context or background on the  whole approach. On
the other hand, maybe it didn't matter at the time since the more
important thing (pragmatic?) for us was to learn 'things' that would
get us decent jobs.
