# About **UPSC (Mains) Maths Optional Syllabus**

We (Ramanasri Institute) are going to discuss complete and detailed UPSC (Mains) Maths Optional Syllabus in the year from 2018 to 2019. UPSC (Mains) Maths Optional Syllabus is also called IAS (Mains) Maths Optional Syllabus. But IFoS (IFS) Maths Mains Optional Syllabus is different from UPSC(IAS) Maths Mains Optional Syllabus. What we have noticed is that both of these syllabus are almost 80 percent is the same. A few topics which are in UPSC(IAS) Maths Mains Optional Syllabus are not present IFoS (IFS) Maths Mains Optional Syllabus and vice-versa. You can also see the difference between these syllabus which we have given in the last of this page.
