Difference between Acrobat X Pro standard edition and Student/Teacher edition - Please help

Hi,
 
I am planning to buy the Student/Teacher edition of Acrobat Pro.
 
But I have a few newbie questions/doubts :(
 
1) Is there any difference in functionality between the two versions?
 
2) Is the Student version time limited...ie license expires after a time...?
 
3) Will Adobe accept student from non-computer/IT related fields...I am a med student.
 
4) Most importantly, is LiveCycle included with the package?
 
5) Lastly, do they have Student discount for the Acrobat X Pro Suite (with PhotoShop CS5 included)
 
Any help would be appreciated! Thanks.
