2015 OC results

This is the best ever set of results. While the top student did not achieve highest OC profile of 276/300 of last year, there are a lot more students and great results overall. About 65% of the students achieved OC placements or scores good enough but they only picked schools with too high entry cut-off scores. The performance in the OC test pretty much matches with expectations from OC trials.

A few interesting observations could be seen from the results. When students scored well in the OC test and their school did not give marks, the OC profile is generally better than expected. However, if they scored poorly, the OC profile would be worse than expected. It also looked like in 2015, English difficulty has been brought down a little. This pushed the importance of GA even higher. It would be  possible to do really well just by having a great GA score while English and maths were at the average.

Upcoming 2015 OC test results

There is a lot of reasons to be very optimistic about the coming OC results. There is a strong growth of membership in OC group. The kids show a lot of strength as they spent 6-10 months on the program. What is really interesting is a chance to compare a kid who has no tutoring whatsoever and others who have tutoring at various places. Yet they came neck to neck on performance leading to the trials and the average of the OC trials look quite close too.

As the kid who did not have any tutoring spent so much time on all parts of the Mathemafix program to enrich knowledge in science, general knowledge, vocab, ... there is a possibility that this kid will score better in the OC test. However the others with tutoring and trials at other places are also very competitive and have an edge in speed.

There is only 7 more weeks until OC results come out.

2015 candidates vs. the past candidates and their OC profiles

NSW selective test performance in 2015

The results for 2015 look very strong. Out of the students on Mathemafix going for this test, about 1/2 were former OC candidates growing with this website since year 4. They were the strongest and achieved very high performance. Some did not do so well in OC test but eventually got very good selective result. This shows the advantage of following a consistent method over a long period of 2 years. It also shows that the preparation program here is very strong and mature.

The 2015 selective test raw marks show that mathematics is harder this year. English marks look better than last year probably due to the massive emphasis on English here. Students were encouraged to read a lot more, do more English tests, do Wordlist, VocabTest and write as much as they could.

Students also won 3 scholarships and mostly turned them down in favour of excellent selective choices. Again it shows the maturity of the program focusing more on English and general ability.

The raw marks look very impressive. However they also clearly shows how important English is! In this game English and GA provide the bulk of strength for the selective profile.

The averages of selective trials on Mathemafix also show that the trials are positioned very well. If students could reach 90% in trial average, they would be fighting for the top position in the state (about 280/300). So far the highest profile on record is still at 254.92/300 (in 2013).  The highest profile was actually 261/300 (in 2014) but it was from a student who only spent 4 months on Mathemafix so that one did not really count as a real Mathemafix user. The highest profile reported from the public side of Mathemafix (where students did the free trials) is 265.15/300.
