Leadership & Impact

"Being guided by Mr. Sibtain Ahmed – a very enthusiastic and friendly Team Leader – helped me quickly integrate into the class right from the very first sessions. He not only provided detailed and clear instructions on how to complete assignments throughout the course but also always tried to bridge the gap between group members by regularly checking in on everyone's situation, sharing stories, and encouraging everyone to talk about their personal interests to find common ground. Thanks to that, the class atmosphere became warm, cheerful, and everyone could easily support one another. I am truly grateful for his dedication and hope to continue learning with him in the future."
