    there is a variation in marks of botany and zoology...previously both the subjects are for 180 marks...but now botany is for 200 and zoology is for 160 according to the weightage...will this change occur in neet 2020 examination?


      The total marks for Botany and Zoology put together would be 360, as confirmed in the latest offical notification also. NTA does not prescribe relative weightage of zoology or botany within the overall 360 marks. There could be variations year to year in the proportion of marks for Botany and Zoology.

      This blog describes the expected weightage based on our expert analysis of the latest trends. The actual weightage of topics in NEET 2020 could be different from what is stated here in this blog.


    As per the announcement NEET, JIPMER and AIIMS are merged. So, will the questions be purely based on NCERT, nothing out from NCERT?? Will biology and chemistry questions not be asked from outside of NCERT??


      Tejasvi, the announcement simply states that selection for JIMPER and AIIMS shall also be made through NEET. The announcement nowhere states that JIPMER and AIIMS admission tests have been merged into NEET.

      If you look minutely, there's a lot of difference in the question that you have asked and the announcement made by the Govt. In case the tests are merged, yes obviously there could have emerged a new pattern, probably accommodating the difficulty levels of AIIMS and JIPMER too. But the simple announcement is that selection for AIIMS & JIPMER would also be through NEET.

      So, we expect that there would be not much changes in the level of questions or pattern of questions in NEET 2020. This should largely conform to the difficulty levels and pattern as per NEET 2019, with may be, minor variations.
