YOUNG business boffins at Castlebrook High School in Unsworth have certainly proved themselves to be the "write stuff."

For their Adults' Guide to Teenagers handbook has helped the teenagers triumph in the Bury Young Enterprise interim awards.

The school's "4U2NV" squad won the "best overall business" accolade, beating off competition from 11 other Young Enterprise teams.

Under the scheme, schoolchildren and college students receive their first taste of business.

They sell shares, elect a board before manufacturing and marketing a range of goods under the guidance of a designated representative from local business.

Castlebrook High took the honours at the interim presentation and awards held at the Elizabethan Suite in Bury. And the fact the school had entered the competition for the first time made their victory even sweeter.

Young Enterprise runs from each September to April. Now, all the youngsters will be using the lessons learned this week to prepare for the finals to be staged in March.

Castlebrook High's mini-company had concentrated on putting together up-to-the-minute problem-tackling and fun handbook to accompany the often troublesome teenage years.

The manual, which also deals with a range of hard-hitting issues such as drugs, sex , bullying and alcohol as well as fashion, TV and music, is aimed at adults.

Now the handbook, which already has a growing waiting list of prospective buyers, will be printed soon, with all costs met through sponsorship.

Young Enterprise regional development manager, Mrs Charlotte Chadwick, said: "Castlebrook got the highest marks for their on-stage presentation and display stand.

"While many other teams chose to market a number of products, these youngsters just concentrated on the one, which is the guide."

Judges were Mr Colin Nichol, Mill Gate centre manager, Mr John Chadwick of Chadwick's of Bury and Stella Selva, a former Bolton Young Enterprise winner.
