What you want to ask is what should I do if I can't find a group for my college group homework? Ask teachers for help, contact classmates, etc.

1. Explain the situation to the teacher or teaching assistant in charge of the homework, ask for the help and guidance of the teacher or teaching assistant, and help find a suitable group or arrange to join other groups.

2. Contact the classmates you know and see if there are any students who are not in the group. You can form a new group with each other or join the existing group.
