pehle baat ko thora smjha kro.. without any prior understanding things one should not say so.. and it is now wrong.. go to BAHL and ask all this from them? got it? grade of mto is also same ie og2 but bahl offers direct og2 to those candidates who have scored best after the score set fot MTOs.
direct og2 no doubt is lower than mto in terms of growth & par etc. hope you got it.
