Customize Wordpress Plugin -- 2

I have installed a WordPress plugin called "Quiz Maker". I need someone to add a simple feature to the plugin: Store the incorrect answer count to an existing database table as soon as a user completes a quiz. Currently, when a user completes a quiz, the results are stored in a table "aysquiz_reports". The table already has the column "corrects_count". What I need is add one more column called "incorrects_count". That is whenever a user takes a quiz, the number of incorrect answers too should be stored in this table along with other data. I request you to install the plugin "Quiz Maker" (Pro version) in your WordPress site in order to better understand my requirements. I can send it to you once you get the confirmation to do the work. The free version of the plugin is available here: [login to view URL] Please note that this is an urgent requirement, which I prefer to be completed within the next 12 hours.
