About IFoS/IFS Mathematics Optional Syllabus
Getting a good idea of the About IFoS/IFS Mathematics optional syllabus is vital for preparing for the IFoS/IFS Mains examination. Usually, two exams are separated by 2 months: the IFoS/IFS Mains exam and the Civil Services Mains exam. During the second exam, candidates can study the additional concepts for the remaining 2 months. The IFoS/IFS examination is not difficult as you think, so it is essential to prepare properly.
Interestingly, the IFoS/IFS mathematics syllabus is almost the same as the UPSC/IAS/Civil Services Mains Maths Optional Syllabus. The only difference is the paper 1 & paper 2 are already mentioned above. If you're unsure about the exact IFoS/IFS syllabus, you can find it here.
The IFoS/IFS Mathematics Optionally Syllabus is similar to the UPSC/IAS/Civil Services Mains syllabus. However, there are slight differences between the two. While paper 1 has an identical syllabus, paper 2 is slightly different. To avoid confusion, it is good to study the two sets of papers before applying. So, you can focus on which part you want to concentrate on.
IFoS/IFS Mathematics Optionally Syllabus: The IFS/IFS Maths Optional Syllabus is the same as the UPSC IAS/Civil Services mains syllabus. There are some differences in the paper 1 section, but the overall syllabus is similar to the IAS/Civil Services mains exams. Read this article if you are looking for a detailed overview of the IFoS/IFS Maths Optional Syllabi.
You'll need to take the optional subjects seriously. You'll need to know the important topics of the syllabus to be successful. For example, Ramanasri Sir, the IFoS Mathematics Optional Syllabus will cover the IFoS/IFS test questions. It will also include the IFoS/IFS subject and the Mains test series pattern. Aside from this, you'll need to be able to answer many essay-related questions.
The syllabus for the optional subjects is similar to that of the civil services. However, there are fewer vacancies in civil services. The eligibility criteria for both the civil services and IFoS are the same. You'll need a bachelor's degree in a maths-related field to qualify for the exam. If you've got a diploma or honors degree B.Sc., in a maths-related field, it's best.
The IFoS/IFS Mathematics Optionally-Syllabus should include all topics. Therefore, you should be familiar with these subjects. In addition, it would help to familiarize yourself with modern algebra or abstract algebra concepts of these maths optional subjects.
