Should I switch to preparing for boards on the basis of QFT-1? Please be brutally honest

Can someone be completely realistic and tell me if I chance at doing jee...Not seeking copium or anything, I just wanna know if I'd be better off studying for boards and maybe private college entrances rather than wasting time on something that might have slipped out of my hands or for which the ship has already sailed. Additionally if you could provide some advice I would be really grateful.
