I passsed my bike and theory test in 98' 

 
  Now im learning to drive again, i did so for the first time 3/4 yrs ago but didnt finish due to commitments.  Then I was told my theory test would be valid still. 
 Now im being told that it is only valid for 2 yrs??  
 Surely if i have been in bike for 8years its a bit late now for a theory test 


 
  Somone else told me i passed before the 2yr limit was introduced, anyone had any experience of this? 
 How about if you go from car to bike? do u need to do theory again???
