ISB YLP (class of 2017)

Hi,

I am applying to the ISB YLP. What I wanted to know was that how many students are selected in total in the YLP? Do the YLP students join the regular PGP class after 2 years of work-ex? Does the ISB (after acceptance to YLP) help in the placement process or in any way influence the firms where you could be working for the 2 year duration?

Also, i recently gave my GMAT and scored a 680 Q50 V31, how does that affect my chances of getting through?
Any help would be appreciated!

Thanks!
