French is different language has some exception in writing but that doesn't mean,it's hard language,just you should memorize the words like that with mute (e) or with accents,because in French we use accents for (a,e,i),so the important which you should know it,it's the pronunciation of those accents with(i,e,a) some of them has a same pronunciation,but you can search it in dictionary and check it in notebook,to remember it well,the rule of this accents just to make meaning to the words or to be easier in pronunciation
that's all
good luck
