I’m in an acting class now. How many times should I rehearse with my scene partner?

Although, there are instructors who feel that rehearsals are not needed at all, I feel that rehearsing alone first is always a good thing, because you hear your 'own' voice. Once you do that, I would suggest getting with your partner as swiftly as you can allowing yourself the time to rehearse twice a week. This will help to give you confidence when you get on the stage. A word of caution - Always communicate with your instructor if your partner seems lazy, not rehearsing with you, or hard to reach. Those actors should not be in training. That deteriorates any school. Tell your instructor immediately. Please don't worry about being a tattle tale. Be A Tattle Tale!!! You deserve to have the best actors of the same mind around you. Give it all you have and you shall see some type of a reward ...
