ETEA past paper 2011

This is a short collection of questions which came in ETEA 2011.Educational Testing and Evolution Agency asyou know is one of major testing service like NTS and those students who pass it get admission into good universities and colleges.Be sure to check ETEA model paper and other past papers uploaded on NUSTweb.

ETEA 2011 paper
