It sounds like you want a new feature:
INSERT INTO test (...) SELECT * FROM student
ON CONFLICT EXECUTE FUNCTION do_your_stuff(excluded);
Sounds like it could be useful, but somebody would have to design it
fully and implement it.
Or maybe just
INSERT INTO test (...) SELECT * FROM student
ON CONFLICT DO NOTHING RETURNING excluded.*;
