dear aspirant,

yeah ,the  practical marks also be calculated along with plus two marks .the total aggregate percentage is taken for the exam you need at least 50% of the marks. for keam exam they only calculate maths ,physics ,chemistry marks 

hope it will help

thank you.

According to the eligibility criteria of KEAM 2019, you need to have a minimum of 50% aggregate in mathematics alone and 50% if physics, chemistry maths alltogether. The total marks reflected in your marksheet will be considered and mostly they include theory+practical. So yes your practical marks indirectly can affect your admission process. 

Hope it helps.

Thank you.
