I was really happy to get your letter. It seems you're worried about how I'm getting ready for the important final exam. I want to calm your worries. You know I always take my studies seriously. Right now, I've finished making my notes and I'm following a schedule to prepare.
I've already gone over everything I've learned. I'm going through the important topics many times. I'm also looking at the less important ones, just in case. I'm feeling positive about doing well. But please, pray that I can achieve my goal. Send my best wishes to dear father and give my love to the younger ones.
Your loving son,
