From searching for something he mentioned, I also found the below website, which has posted a lot of articles from not long after Andrew went missing:
Gosden, Andrew Sept 14 2007
There's some things that I wasn't aware of, or things that have been clarified better than I knew previously, such as:
"The night before had been a standard evening at home. The family ate together and
Andrew played a jigsaw game with his father on their computer"
"It took only three days to establish that Andrew had arrived in London at 11.20am on the Friday. It would take
another 24 days before the CCTV footage of him leaving Kings Cross was discovered."
"Martin Taylor, one of his teachers, said that Andrew would comfortably achieve a first-class honours degree in the subject at Oxford or Cambridge. He's quite a shy lad, but he has a fantastic smile and I've never seen him down or sullen, Mr Taylor said. Andrew is deep and mature beyond his years. Hes quite self-contained and happy in his own company, but hes not a loner.
He always had a little posse of friends with him."
