UPSC combined geo-scientist Syllabus 2021:The recruitment process for the vacancy of UPSC which was released through the official notification of the UPSC Recruitment Board is about to start soon. Where 40 will be recruited.
So you can understand how much competition there is going to be. If you want to survive in this competition, then you have to do smart work along with hard work.
- First of all, you have to study the syllabus properly
- The previous year’s cut off should be studied.
- You need to know the exam pattern.
- By looking at the UPSC combined geo-scientist Syllabus 2021, you will understand which place is stronger, which place is moderate and which place is week.
- Understand that a strong place should be kept in a little touch while studying. The average place has to be made strong, and the week place has to be made average.
In order to do all this work, we first need to know the proper UPSC combined geo-scientist Syllabus 2021 and exam pattern which is discussed very well below.

You can emphasize a few things in Stage 2 that can help you crack the exam.
- Math needs to be practised well, especially trigonometry, algebra
- General Intelligence and Reasoning helps you to rank directly easily, so you should practice General Intelligence and Reasoning very well from now on so that no questions on this subject are wrong in the exam.
- The science subject is a little hard for the students of general background, but if your strategy is correct, there will be no problem. So in the case of science background students, the subject will be very easy. Because more questions come from 11th and 12th base.
