Need an honest opinion

Hey guys! I'm an international applicant planning to apply to Bocconi Global Law in the early session. My gpa in both years is 10 but I'm worried about the Bocconi law test. I did a Bocconi law test simulation and got 23, which is very low. Do you think I have enough time to prepare for the early session and how realistic it is to improve my score in a few months? By the way, I'm not taking the LSAT because it's much more expensive than the Bocconi test. Thank you for your answers in advance!
