Being LAE or certifying staff, you have be responsible and accountable for all the item that you have signed off (release). As aircraft is not like car when driving your car if spoilt you still can park at the roadside where aircraft you when flying you can't park in mid air when spoilt. So it's a high responsibility job being LAE or certifying staff, where if you are found guilty of causing any aircraft accidents you can be guilty of criminal prosecution and suspended by company (i am not trying to scare not to become LAE or certifying staff ).

So get a more general degree first, if you still want to become LAE then only narrow down. Don't get too narrow down on your studies to aerospace if you are not 100% to join the industry after you finish the studies.
