# BPSC Statistics Optional Syllabus

BPSC famously known as the Bihar Public Service Commission conducts examination for the recruitment of civil servants to serve the state of Bihar. Candidates who compete the exam successfully hold key positions in the state administrations such as SDM, DSP and many other such coveted posts. This exam consists of three stages namely Prelims, Mains and Interview. In the mains examination of BPSC CCE an aspirant has to chose one optional subject which is of qualifying nature i.e. he/ she has to score a number which is equal to or greater than the qualifying marks as per the category of the candidate. Statistics optional is one among them. In this post Statistics Optional Syllabus for BPSC is discussed.

## BPSC Statistics Optional Syllabus FAQ

### How many sections are there in BPSC Statistics Optional?

There are two sections of the syllabus for the BPSC Statistics Optional.

### Is the syllabus of BPSC optional for statistics and BPSC statistics asked in GS papers same.

No, syllabus for both is different. However, people who have statistics as BPSC optional paper will have an edge in the GS papers also as the syllabus for BPSC Statistics Optional Paper is extensive and overlaps with the GS portion of the subject.

### Is Statistics for Optional and General Studies Paper Same in BPSC?

No, you don’t have to confuse between statistics that is asked in BPSC Mains General Studies Paper and that is asked in the optional. The statistics that is asked in BPSC Mains GS is mandatory for all candidates to solve but it is upto the choice of the candidates to choose any optional in BPSC Mains.
