Key word transformation including the word "remember"

Ok, in this exercise I need to rephrase the following sentence into another one including the word “remember”:
“I’m sure we studied this unit last year.”
Obviously, the most natural sounding answer would be “I remember studying this unit last year”. I was just wondering whether “I remember that we studied this unit last year” could also be a correct option. Thank you.

Yes, both ways are fine.
