since watch is not allowed during examination neet ,how to see the time while doing paper ;will there be wall clock in side the exam room

Dear Verma, yes every examination hall will be provided with a Wall Clock and you can always check it in between. Simultaneously you may also hear the invigilators call out the time. It is their individual choice either to call out the time every half an hour or not. But you will have a wall clock which you can refer to keep a tab on the time you are spending and the time left to answer the remaining questions.
