Hi Hung V., I noticed your profile and would like to offer you my project. We can discuss any details over chat.
i need 2 simple features added in the WP pro quiz plugin for my website. its a free and open source plugin.
1. i need to able to specify how many questions will be selected randomly " from each category". currently it doesn't allow to set specific number of questions to be shown from each category. it only allows to set specific number of question from the whole quiz.
2. i need 0.25 negative marking for each wrong answer. no marks will be cut for unattended questions.
