Hey AN89JX, you asked a good question but I guess it depends what your idea of fluency is and how much you put into the course. If you define fluency as being able to get around a Spanish speaking country, than yes I think two beginner classes would be enough. But if you want to read literature, watch things without subtitles and understand everything being said to you, I would say no. It also depends how long the courses are and how intense they are. Every language course is different so you never know. While taking the class if you want to be fluent, I'd study very hard and immerse yourself in Spanish culture as much as you can
