I have a presentation where we have used branching to hidden slides. I have 10 scored assessment questions the user may not skip. Now, the problem is that if I place the hidden slides at the end of the presentation, it does not allow me to access them probably becuase they come after the assessment quesitons.  
 
If I place it at the beginning it works but from a hidden slide, if I press the next button, it goes to the first slide. I tried placing it just before the first assessment question (the quesitons are not together, they are scattered across the presentation). Now, if I click teh next button from the hidden slide, it goes to the first assessment question but it should go to the root page (the page from I reached here).  
 
Anyone knows any workarounds? Thanks in advance.
