CSIR NET Earth Science syllabus is divided into three parts i.e.Part A, Part B, and Part C.
The syllabus of Part A is of General Aptitude type. So, there will be no difficulty for the aspirants to solve the questions of this section.
But, the syllabus of Part B and Part C is quite hard to cover.
The difficulty level of questions asked from these two parts is also moderate to high. So, for the ease of aspirants, here I'm sharing some important topics from CSIR NET Syllabus that can help you to boost up your overall score.
Atmospheric Science - 30 to 50 Marks
Geomorphology - 15 to 20 Marks
Oceanography - 60 to 65 Marks
Geophysics - 50 to 55 Marks
So, these are some topics from where mostly questions are asked.
