if i get less marks in 12th board, maths,but good in phy and chem.And i passed the entrance exame,will the university see 12th result?

Hello Mehtab Aashir,
For getting admission in an university you need to qualify an eligibility criteria. If you score less in maths but good in physics and chemistry and your total percentage of PCM is able to cross the barrier of eligibility criteria then you would get admission there. For example, if you want to get admission in NIT, IIIT or IIT then along with qualifying their entrance exam you need to score a minimum of 75 % in 12th...
Hope it Helps...
