Calculus is useless, until it is not at which moment it turns to incredible help. You don't need to go super deep, bit basics are occasionally quite useful. More importantly, if you learn only what you strictly need right now, your work possibilities will be very limited.
Also, for some reason, I found abstract algebra related to objet oriented design - similar kind of thinking.
This is free course - they won't be in unfortunate 3000$ lock you was. (I think calculus is useful, but I don't think it is worth paying that much money.)
