'mechanical waves' (sound) has accounted for approximately 12% of the total marks. chemistry 'organic chemistry' has the highest weightage with mean marks of 36%. topics like 'isomerism' and 'name reactions', and 'stability of reaction intermediates' should be thoroughly covered. 'physical chemistry' is a close second with a mean weightage of 33%. 'inorganic chemistry' and 'general chemistry' account for 21% and 10% of the total marks. inorganic chemistry should be prepared by studying the group properties and periodicity. mathematics 'calculus' accounts for about 30% of the total marks in jee screening. 'algebra' has a weightage of about 23% of the total marks. 'analytical geometry' has a weightage of about 20% of the total marks. the topics of 'vectors and 3-d geometry' and 'probability' have a weightage of approximately 6% each. 'trigonometry' carries a weightage of about 9%. it has been observed that this weightage was as high as 17% in jee please feel free to post as many doubts on our discussion forum as you can. if you find any question difficult to understand - post it here and we will get you the answer and detailed solution very quickly. we are all iitians and here to help you in your iit jee preparation. all the best. regards, askiitians experts badiuddin",
