Hi Everyone I need Your Help for Assessment

I will usually tackle this by assigning each chapter a variable, such as "Chapter01Complete" and "Chapter2Complete." The initial values are 0. 

On the last page of each chapter, I have an action On Show to Modify Variable, where the variable is the applicable ChapterxxComplete and set it to 1. 

On the menu page, I would add a hidden button that takes the student to the assessment. Add an action to show the button On Show (the page level) only when ALL of the following are true: Chapter01Complete = 1, Chapter02Complete = 1 and so on.

There are more elegant ways of doing this, but this provides a decent start.
