Hi,
I'm in the same boat and have just started a small website to help people like us.
I have been finding it very hard to find any information on the internet, no-one seems to be really discussing these transfer tests and it was just by chance that I saw this post while I was scouring google and joined this site.
So far I have only put together a few pages but as I find more information I am adding it to the site.
At the minute I have just put links to a few forms for both the AQE and PPTC exams.
I was speaking to some other parents about the practice papers, we were all being told that it should be a paper a day with one day break a week but the practice papers and books in the shops seemed so expensive compared to what I was looking at online.
I ended up taking the isbn numbers and names of any papers or books that people were recommending to me and I am starting to put the links to them on a page too(don't know how successfully,I'm getting help with the technical things)
I don't know if I am allowed to post links here but I will put it in and see if the post gets edited by the moderators.
I call the website 'Northern Ireland Transfer Test' and the address is www.nitransfertest.co.uk
Now that I have found a place to chat I will be on here too.
