if I get more marks in bifocal subject instead of chemistry, can then bifocal subject marks be considered in pcm instead of chemistry, to join engineering college ?
Hii,
No, to join engineering colleges you have to get the minimum percentage of marks required for the perticular college in Physics, Chemistry and Maths.
Scoring good in bifocal subject will help you improve your overall percentage as best 5 would be considered. But it will not replace the marks you got in chemistry for engineering colleges.
