OBS is fun, it not all hard work, morning PT and mosquitoes. They let you have time to reflect abt yourself. Your time with SIA will comprise of many high and lows, ups and downs. You must be mentally prepared for the challenges ahead and not give up on yourself. Alot of things may seems hard to achieve and almost impossible. I can tell you for sure you guys will be having a hell of a time in seletar with ATPL. Worst then A levels and uni combined. And flying in Jdk is alot of mind games, but never give up and always encourage n support each other. It can be done.
Learn as much as you with an open mind, be humble and have fun. Just watch yourself, don't get caught with yr pants down.
Welcome to the brotherhood guys.
