It looks like you’re asking for a (or feature suggestion) for a site named quackprep[.]org (note the zero in place of the 'o').
Before listing a feature, a quick caution: Using a domain that mimics a legitimate site (like quackprep.org with a zero) is often associated with for exams (e.g., USMLE, MCAT, etc.). If that’s your intention, I can’t support or develop features that help with exam fraud or credential theft. quackprep.0rg
