When does MIT receive and process Sat II scores?

Getting a little bit worried about my Math II and Chem test arrival. I sent my November Math II score on January 1st and this site: https://collegereadiness.collegeboard.org/educators/higher-ed/scoring-changes/sat-score-delivery-dates says that scores will be released weekly but it has still not arrived. I took the January chem test and I understand that score will take longer to arrive because but I’m afraid the same thing may happen.

Did I mess up somewhere or is this normal?
