NEET 2020 CHEMISTRY SYLLABUS
NATIONAL LEVEL OFFLINE TEST
The first step towards preparation is the right knowledge of syllabus. NEET 2020 Chemistry syllabus is based on the topics studied in class XI and XII. The syllabus is prepared by MCI by taking into consideration the syllabus of all state boards.
NTA has also cleared the rumours of changes in the syllabus by releasing an official notice. The syllabus is still the same as it is mentioned in the official brochure.
NEET chemistry syllabus is divided into various subsections which require thorough preparation. However, most of the candidates find chemistry to be an easy and scoring subject.
In NEET 2020, a total of 45 questions will be asked from chemistry. All candidates are advised to go through the exam pattern. Check NEET Exam Pattern
