KwaZulu-Natal's top-performing Correctional Services inmate has called on young people to refrain from drugs and negative influences, saying education has given him a second chance at life. "I was a drug addict before, and I got out of school. There's no future in drugs. It is either they kill you or you go to prison," Westville Prison inmate Sandile Stangoni told News24 on Wednesday. He was speaking on the sidelines of the KZN leg of the 2019 matric top achievers event. Stangoni, who managed a whopping four As, said there were many challenges with studying in prison. He has been imprisoned since June 2018. "It has been a difficult year. It is not easy studying in prison. There are a lot of things that you cannot do in prison. Many things are happening around you."WATCH: Westville Prison inmate Sandile Stangoni says he faced many challenges while writing his #KZNMatricResults19 @News24 @TeamNews24 pic.twitter.com/N0LT7lPX0W— Kaveel Singh (@kaveels) January 8, 2020 He however persevered, refusing to give up. "But I told myself that nothing is more important than education. So, I went all out and studied - sleepless nights. I'd like to thank the effort my teachers made, who helped me to get where I am today."Stangoni said sometimes it was not easy to get information for assignments. "We also don't have some study notes, so you have to share. But again, through the excellent job of our teachers, I made it."He said his strategy was consistency and getting help from others. "During my exams I formed study groups, studied hard, gave myself time to sleep and had lots of water."While he still has at least another year to serve, Stangoni said he hoped to study architecture in 2021. "I have parole next year."Poor resultsMeanwhile, KZN saw a marked improvement in the pass rate with a 5% increase to 81.3%, up from 2018's 76.2%.
