Name of a movie about a group of nerdy kids that wanted to have wild summer before going to college

I watched on this movie on netflix in 2018. I can’t find anything on Netflix that looks like what I remember. It was a group of many four kids. The main guy got a job as a tennis instructor at a country club and ends up getting with a lot of the moms there. Another guy had an indian penpal gf and she shows up at the end of the movie. At the end they have a party with all the people from their high school. That’s all that I remember. Any help would be appreciated.
