A black page is provided for rough work at the end of each part, 9. REMEMBER YOU HAVE TO SHADE ANSWERS ON A SEPARATE OMR SHEET PROVIDED 10. Answer to each question is to be indicated by SHADING the cirele having the number of the correct II. 12. 13. The candidate need not return this Question Paper booklet and ean take it after completion of the alternative in OMR Sheet firom among the ones given for the corresponding question in the booklet. Now turn to the next page and start an:wering the questions. After the examination, you should hand over the OMR Sheet to the Inviglator of the room examination. No candidate should leae the examination hall before the end of the examination Mental Ability and Scholastic Aptitude Test Name of the Candidate : Registration No. School Name
