GSoC Applicant seeking Guidance (3PRs Passed Checks )

Hi, everyone ,
I am CS student and I am very interested in contributing to this project #8 and applying for GSoC this year . Since the application period is coming soon ,Ihave
been trying to contribute and learn more .
I have already submitted about 3 pull requests,and they all passed the checks ,but they were eventually closed .
I wanted to ask if it is still possible to apply and be considered for GSoC even if idon,t have an accepted PR yet.
Thank you for your time and support.
