Yes u can mail them dere s no harm in it bt its all ur luck whether they ill respond to it or nt... Also made an enquiry they said same thing wait till firat week f july..
U need not to worry buddy. It does nt mattr whether u fail or pass provided shld be less than 22 .... Bt stick to the same course in to avoid unnecessary complicatications if necessary
