Seating arrangement would describe the overall plan for accomodating the approximate number of students expected.

A sitting arrangement might describe some unusual feature about the chairs - eg., you're gonna sit on the ground - or you're supposed to bring your own personal whoopee cushion.

As an aside, an "arrangement" is usually "made" rather than "done," unless it's floral.

"Seat" is also a verb. The site just ate my post and I don't have the energy to type it all again.

i thought seat is a noun and thus cannot be converted into "seating" as a verb - on the other hand - sit being a verb can be easily made into "sitting". however now i see that "seating arrangement" is the correct form. but can anyone explain why it should be so?????

Broadly speaking,, consider these meanings.

seat verb, meaning find or arrange a suitable seat.

sit verb, meaning cause your body to be supported by a chair.

An arrangement is not 'done'.

Say

eg Seating arrangements for the examination have been made in the Library hall.

eg Seating for the examination has been arranged in the Library hall.
