Today I received a message from my school admin. that from now on I'll have my exams in Royal Palm. Previously we were informed that all our exams will be in Garrison Club. Is it only with me or someone else's exam center has also been changed during exams. Will it cause any difficulty to me? Like our school's seats will be spread over various exam rooms or anything?

but how do we know the direction of the rays after making the images ? do u join them to any specific part of mirror?

i do not actually understand your question sorry but you can find image positions by extending your reflected rays to behind the mirror.......(and see point of intersection)
and keep angle i=angle r always in reflection .......
