User cannot review input before submission
If the user can change or delete legal, financial, student exam responses, or unrecoverable/unintentionally modified or deleted data, the changes/deletions MUST be reversible, verified, or confirmed.
Online legal, financial, test/exam taking, and large data transactions can have serious consequences. People with disabilities may be more likely to make mistakes - such as transposing letters or numbers or pressing a key by mistake. It is important to help detect mistakes before taking an action that could result in serious consequences by giving people an opportunity to reverse or verify or confirm the transaction. Providing the ability to review and correct information gives (all) people an opportunity to detect a mistake before taking an action that has serious consequences.
Fix this issue by allowing the user to review and edit the information or answer(s) before submission.
