Reset score for dedicated compared to when initially learning

we need to be able to delete not used exams or school exams

How can I delete an old exam that was created by aciddent or submitted too early. I dont see a red x or delete option on my tab. 

Like other question banks, allowing users to reset the question bank independently, rather than relying on customer service, would be beneficial. I had to conduct extensive research for what should have been a straightforward request, only to discover that I needed to reach out to customer service for assistance.

Be able to see progress of performance by specific subjects over time. e.g. if I see I am lacking Microbiology. Then review First Aid. It would be great to be able to see if my Microbiology performance improved over time.

Add the ability to sort by the "peer correct %" header when searching questions.  This would allow us to prioritize information that is heavily understood by the rest of our peers when filling in gaps during review.

Be able to filter out what exams/ questions you have reviewed or not reviewed.

Sometimes I'll take several exams in a row and not be able to remember if I reviewed the content or not without going through the questions first.

populate an ongoing list o fmost missed topics. Even better if it would readjust based on what you're missing more frequently

Be able when making a new exam to filter questions by "guessed" so you can go back and do them
