In NEET Examination the weight age is always 50-50 but sometimes out of 45 questions if we categorise,  I can not say 50-50 may be 45-55 like that or little bit keep changing. In Physics there is no difference but in Biology, Chemistry not more weight age from first year or second year, Nobody mention so far. But in total syllabus of Class 11 ^th & class 12th almost 50-50% is divided in my opinion.
