I think this is actually a very good discussion topic as depending on what type of Christian you are, there may be a different answer. However, I'll give my own take on it. No, getting baptised is not required to be saved to get to heaven. The bible says that as long as you accept Jesus as your Lord and savior and believe that he died for our sins and that you ask for his forgiveness, you are saved. BUT, if you can get baptised, do it. You are showing God that you would do anything for him, and it doesn't hurt to try to be as close as you can to him. Doing whatever you can to follow what God says is the best way to have the best life you can.
