Question: Mention the names and credits of course registered by the students who were under the supervision of female professor with the highest teaching ability.
Evidence: female refers to gender = 'Female'; highest teaching ability refers to MAX(teachingability);

SQL:
SELECT T5.name, T5.credit FROM RA AS T1 INNER JOIN prof AS T2 ON T1.prof_id = T2.prof_id INNER JOIN student AS T3 ON T1.student_id = T3.student_id INNER JOIN registration AS T4 ON T3.student_id = T4.student_id INNER JOIN course AS T5 ON T4.course_id = T5.course_id WHERE T2.gender = 'Female' ORDER BY T2.teachingability DESC LIMIT 1
