Sample practice tests
These sample tests are very
old and they put up only as example for people to know the test format and
question styles. It is a bit silly but the Selective Practice test for
year 6 is more or less only suitable for year 4 students to practice for
OC test. So when a year 6 student who have NEVER seen these papers
before and could score 90% on them, do not hope for much, probably only
enough to enter one of the low selective schools ranked about 15th-20th
in NSW. The NSW OC Practice Tests are now only suitable for year 3
students.
