Form 108 and 119 in triplicate?

my Articleship got over finally after a lot of hurdles. i have filled Form 108 and 119 in triplicate and got it signed from my boss. I have taken 160 days leave in 3.5 years. my questions are

Should i send the 3 copies of form 108 and 119 to the institute or only one ?
Is 160 days leave allowed or will i be asked for an extension ?
How many days will it take to get a reply from our institute?
I have drawn year 4 manually in form 108 and filled up the work experience. is it ok?
