Here are three constructions to avoid using "il faut que" which is followed by subjonctif tense

Avoid subjonctif "il faut que"

"Il faut que j'aille à la banque" becomes "Je dois aller à la banque", which means "I must go to the bank".

"Il faut que je rende visite à mes parents" becomes "Mes parents m'attendent", which means "My parents are waiting for me", slightly different in the details, but the result is the same.

"Il faut que tu comprennes ce cours pour réussir tes études" becomes "Il est nécessaire de comprendre ce cours...", meaning "It is necessary to understand this lesson/course...". Slightly different again.
