Plugin bank of questions for Wordpress - open to bidding

I'm in need of a plugin that works like a bank of questions to generate lists of questions for the user from a filter (7 different categories + amount of questions). And this also serves to generate lists to incorporate [shortcode] into internal pages. Questions will be multiple choice and response options must support the image. A model similar to this: [login to view URL] If the generated lists have a countdown timer and the system can sort the difficulty of the question by the hit rate, better still. If possible, I would also like to feed the question bank from a pdf, txt, xls or doc standardized so as not to have to pose the issues individually. Important: The plugin must support translations (loco translate), mainly for Portuguese (Brazil) (pt_BR). I am open to negotiating the proposed value. Please send us a quotation.
