11/13/2008 - Some updates over the past 3 months:
DWITE: Due to some errors in their test data, Brian and Hanson only placed 6th and 9th, respectively. Toby was 17th, while Jacob ended up 28th. A good effort by all who participated!

TopCoder: Brian won a TCHS round, while Jacob placed 2nd in another round.
Both Jacob and Brian are now yellow (rated 1500+).
Congratulations to both!

USACO November: Hanson, Jacob and Brian scored 800, 560, and 230 respectively in the Gold Division.
Meanwhile, Toby scored perfect in Silver - he now qualifies for Gold. Congrats! Harun got 561 in the same division.
In Bronze, Saravannan was close to perfect (886) and will be promoted to Silver! Bosco and Hao followed with 600.
Andy and Scott were not too far behind.

08/24/2008 - Hanson is back from the IOI and brought back a gold medal. This is an accomplishment that can be put on par with the olympic gold medals (should be 4 medals now!). Hanson has trained with dedication and earned this gold medal. As the Beijing Olympics ends, this news post will also be my last for this site and I hope that everybody can look up to Hanson as a role model. It shows that not only talent can win a medal but hard work and dedication that really makes the difference. On behalf of our grade 12 year, I would like to say that we were honoured to be taught by Mrs. Plachta and we enjoyed teaching the juniors. This year was a great year (like every year) as we accomplished many goals and surpassed some. Also, be sure to congratulate Guru for entering stage 2 of Google Code Jam (going to compete in NYC) and for being an amazing president of PEG this year. We will be missing PEG as we have gained wonderful memories, knowledge and friends. Thank You and Good Luck to the future of PEG.
(We will be coming back here sometimes and we also hope to update the site again to incorporate a judge).

06/01/2008 - News from the CCC has arrived from Waterloo. Hanson Wang finished second in Canada and he won the gold medal. He will be representing Canada at the International Olympiad in Informatics(IOI) to be held in August in Egypt as one of the top four Canadian students to attend the event. Three of our students (Brian Bi , Guru Guruganesh and Jacob Plachta) won silver medals and two of our students (David Teng and Colman Ing) won bronze medals. Congratulations to all of these students (especially Hanson)!

05/27/2008 - Earlier in the week our 3 teams (senior, junior and intermediate) competed in the ASCL. The junior team finished third with one point behind second place. They got perfect in programming (in fact all our teams got perfect in programming) , but did not do so well in short questions. Compared to the rest of the competition they were the only grade 7 students compared to the other juniors who were in grade 9. Our senior team also finished 3rd and were also and lost on the fourth tie breaker to second place. We did manage to take first place with our intermediate team. The short questions were really hard this year (but Brian got perfect). Congratulations to all the teams and good luck to those of you in the CCC.

05/15/2008 - Today was the final round of ECOO with two of our teams who made it through to the finals. Unfortunately, Woburn #2 could not place but Woburn #1 (Guru Guruganesh, Hanson Wang, Conan Huang and Ray Yau) placed first place and once again inscribed our school onto the ECOO trophy. This is twice in a row so lets try to make it a hat trick!

05/06/2008 - The final standings for ACSL were released. The senior team placed first and the junior team tied for first. Good job to both teams.

05/05/2008 - Today was the ECOO Stage 2 for Central and Western divisions of ontario. Both woburn teams had trouble on question 4 but managed to move on to the finals. Woburn team #1 placed 3rd and Woburn #2 placed 6th. Recently there was the US Open hosted by USACO. In the proctored US Open Hanson Wang finsihed 9th in the gold division. David Teng finished 3rd in the silver division and got promoted to gold division while Jacob Plachta finished 7th. Last but not least, Colman Ing finished 3rd in the bronze division and got promoted to the silver division. For most of the PEG members PEG is already over and only active and members participating in the ASCL are required to come to meetings.

04/06/2008 - Yesterday was ECOO's regional competition and 3 of our teams were competing with 50 other teams from different schools in the region. Woburn team #1(Guru, Hanson, Conan and Ray) took first place and Woburn team #2(Colman, David, Jacob and Harun) took second place. Both teams will be moving on and will compete again in early May. The third woburn team tried their best and came close to moving on but placed 15th. Good try and good job teams!

04/03/2008 - It has been a long while since we've updated with news but we do have good news to share. During March The TopCoder world finals were held at the Purdue University over the March break. 49 top programmers from around the world were invited and Hanson finished 12th. In the last USACO two of our students got a perfect score. Lucia Li and Harun Mustafa got a score of 1000 in bronze division and will be moving up to the silver division. Guru and Jacob got very high scores in their divisions. All three ACSL team won an early invitation to the finals. Our senior team is right now first in their division, and our junior team is tied for second place. 13 students will be going to the final stage held in Maryland at the end of May. In relation to the last new posts the CCC invitations were announced. The cut off mark was 66 and 6 of our students were invited to the second stage (out of 22 from all of Canada). This is our (and any school's in Canada) record. Brian Bi, Guru Guruganesh, Hanson Wang and Jacob Plachta all received perfects and ranked 1st in the contest. Colman Ing and David Teng ranked high enough to be invited into second stage. Congratulations to all of these students.

02/27/2008 - Yesterday, 19 students of Woburn took part in the CCC(Canadian Computing Competition). Four of those students got a perfect score 75/75 which is not only the Woburn record, but the Canadian record - in the history of this contest there have never been more than two perfect scores in the whole country; we never had more than one. These students are Hanson Wang, Guru Guruganesh, Brian Bi and Jacob Plachta. These students will make it to second stage. Two other students who achieved high scores were, David Teng who achieved a score of 72 and Colman Ing who achieved a score of 68 may get invited to second stage.
