Is taking April CSCA worth it?

Hi, I am about to take the March CSCA exam and I just feel like there is no way I will get a score above 60. My target school is SJTU. So I'm thinking about retaking the exam in April. However, university deadlines are uncertain. Do you think universities allow me to send the CSCA score later?

Secondly, I am doubting whether CSCA is really important. There are mixed opinions on the internet about CSCA like how it plays a big part in scholarships or this year's scores are not too significant for admission.

I will appreciate any response
