Diet for Examination.. LOL

Is there any diet for Examination.. ?? 

Yesterday I visit a institution here in Oman which is famous here.. In this they will teach Personality Development, Spoken English and  of course all IT trainings also.. but they don’t know what is VMWare.. ( this institute is one of the test center for VMWare Certification.. in Oman )

There in the notice board I saw one notice but I don’t understand for a moment what diet it is for Examination..

Its funny to see such notice boards in Spoken English institutions.. HAH HAHHA LOL!!
