December scores still not available

Have any of you recieved your scores yet? I took the test and my scores were delayed also. I got a letter that said they are under review. The first time i took the SAT i did a really bad score… I just wanted to know how the SAT worked. This last time I took it I focused more on studying. I think it might cause them to double check due to the variance because i did better on the second one. What does that mean? Could they cancel it? I’m going crazy waiting on it. I dont know what to do! My scores deadlines are almost due. That happened to anyone before? Please help. I am really stressed!
