NEET Chemistry Deleted Syllabus 2024

NEET Chemistry Deleted Syllabus includes topics like Hydrogen, Polymer, Chemistry in Everyday Life, and Environmental Chemistry. This year, the National Medical Council (NMC) has removed multiple topics from the NEET Syllabus 2025 PDF . While a few topics were deleted from the NEET Chemistry Syllabus, the authority has introduced some new chapters as well. Some of the chapters that were added to the NEET Chemistry Syllabus are Chemical Thermodynamics, Chemical Kinetics, Hydrocarbons, and Principles Related to Practical Chemistry. Students must keep in mind to not study NEET 2025 syllabus topics that are removed by the NTA authorities. Rather, students must study the topics that consist of more importance and high weightage as most of the questions will be asked from those topics. Further, students must try to look out for topics that are repeating themselves every year and study those topics as there is a high chance that these topics will reappear this year as well. As per the latest timetable, the NEET UG Exam 2025 is scheduled to take place on May 5, 2025 . The NEET Syllabus PDF is divided into Physics, Chemistry, and Biology (Botany+Zoology). Some significant revisions have also been made in the NEET Chemistry Syllabus. Read the article below to learn more about the NEET Chemistry Deleted Syllabus, topic added, and other latest updates.

Dear student,

In India, B.Sc Nursing admissions are NOT done basis religion. Seat availability for B.Sc Nursing of Muslim students will be based on merit only. However, you can avail some respite as you are a girl student, & in many colleges, seats are reserved for 'female candidates'. 

Also, if you belong to any of the reserved categories like OBC, SC,ST, PwD, even then you will get some relaxation.
