I had a exam‥

Yesterday, I had a exam. I have taken it four or five times. It takes 16000yen to take it once. It's so expensive, but I don't have a part time job. My mother wants me to earn pocket money. I am so sorry, but I intend to work by summer, so please waiｔ! By the way, My score has improved! However, it dopesn't satisfied the requirement, so I have to syudy more!!
