Now there is a new pain which, although different in nature, will require a similar response. It seems that someone on angelfire may have created malicious content as detected by CyRadar, SOCRadar, Phishing Database and Trustwave as currently indicated at...

The HSC exam committee is releasing their solutions on the internet for the first time this year onto the Board of Studies website. Previously very few people have had access to these documents which were never published before. I think most people will welcome the policy change at the Board...

Correct answer to Int. Q30 is 174 (same as Sen. Q29) not 180. Thanks PC for reuploading corrected version. I made a pdf of the solution provided by 3unitz:

Complete solutions for the 1999-2008 3 unit HSC papers are on the net. I've collected the 2001-2008 ones together in a zip file: http://www.angelfire.com/ab7/fourunit/ext1sol2001-2008.zip (1.8Mb) See next post for the 1999 and 2000 ones (not included in the zip file)...

All this nonsense of the Board of Studies telling teachers thou must not teach such-and-such before Year 11 is rubbish. The BOS rules stipulate the HSC cannot be completed over more than 5 years or less than 2 years. Therefore some Year 9 students can (and have done) Extension 2 Mathematics, for...

The process for selecting the Australian team is described in more detail at http://www.amt.edu.au/amocprog.html Note that the selection processes are different for different countries. These other selection processes are described at...

I really appreciate me121's posts on this issue. I think we are of the same heart and mind on this issue. The view that all solutions should be online is probably a majority view. About 99% of students and teachers expressing a view on the issue have supported that one. So if I were a...

In the HSC you won't have access to solutions - otherwise you'll be accused of cheating and get 0. You have to get used to doing papers without access to solutions. So practicing past papers under exam conditions includes not having access to solutions. 7 years ago when I started the websites...

I guess the availability of hundreds of exams on the net seems like a challenge. But I'd like to challenge you in a different way. I'd like you to spend several hours on each question in only 1 exam (one of your choosing but preferably one for which you don't have somebody else's solutions for)...

There's a lot more to maths than exams. "Perhaps I could best describe my experience of doing mathematics in terms of entering a dark mansion. One goes into the first room, and it's dark, completely dark. One stumbles around bumping into the furniture, and gradually, you learn where each...

You can upload your solutions if you want. I've got solutions to all the papers, but generally choose not to upload them for reasons I alluded to earlier. Some other websites also have solutions. I'll only upload solutions if they raise more questions than they answer.
