How to Fill SSC Post Preferences Without Regretting It

After the main exam, SSC opens an option form in which you rank the posts and departments you are willing to join. Allocation is then done by computer: the highest-ranked candidate gets their first available choice, and so on down the list. There is no second round and no change afterwards.

What to weigh

Factor	Why it matters
Pay level	Posts in the same exam sit at different pay levels, which affects salary for the whole career.
Place of posting	Some departments post all over India; others are concentrated in Delhi or in state capitals.
Nature of work	Desk work in a ministry is very different from field work in a tax or investigation department.
Promotion prospects	Time taken to reach the next grade varies widely between cadres.
Physical and medical standards	Inspector and sub-inspector posts have height, fitness or vision requirements.
Extra eligibility	Statistical and accounts posts need specific subjects or marks in the degree.

Rules that catch people out

You are considered only for the posts you list. Leaving a post out means you will not get it even if nothing else is available.
If you are not eligible for a post you listed, that entry is ignored at verification, not corrected.
Once a post higher in your list is allotted, you are not considered for those below it, even if you later prefer one of them.

A simple method

Strike out posts whose physical, medical or subject requirements you do not meet.
Group the rest by pay level.
Within each level, order by posting location and nature of work.
Include every post you would actually join, to the end of the list.
