Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###

### Question ###
What is the A score when the B score is more than 9.15 and the gymnast was in the 2nd position?

SELECT SUM(a_score) FROM table_name_1 WHERE b_score > 9.15 AND position = "2nd"
