It depends on the requirements of your school. Basically, all colleges and universities require graduate students to publish a short paper before graduation, otherwise they can't graduate. If you haven't sent it yet, it's not too late to contribute. At present, the publishing cycle is tight, and 70% of periodicals will not get sample publications until the second half of the year.

Moreover, many schools can't apply for a defense in the end if your small thesis is not published. If you publish a core journal paper, you can directly give up your graduation defense. However, the specific regulations of your school shall prevail. After all, the situation in each school is different. I suggest you talk to your tutor directly, or ask your teachers and sisters to tell you the specific situation.
