Hi All,
I have a Validation Rule where all the fields are required 
Picklist( Category__c ), 
Picklist( Course_Name__c ),
Duration_in__c 
Course_Fees__c  ,but one of the Course_Name__c,  Duration is  not Mandatory 

here I have tried 

AND(
 ISBLANK( Category__c ), 
 ISBLANK( Course_Name__c ),
 ISBLANK( Duration_in__c ),
 ISBLANK( Course_Fees__c ) 
) 
OR 

(ISPICKVAL( Course_Name__c  , 'Java')
 && NOT(ISBLANK( Duration_in__c))


Thanks in Advance
