各位高人,請不要用翻譯工具幫我翻譯以下英文為通順中文,謝謝!

When we stepped into the Form 4 school life, there was an important reminder that there was a big challenge ----the HKCEE ahead Undoubtedly, the syllabus of the HKCEE is much harder than what we have learned before. It meant that we had to work much harder than before. However, even with the foundation that was built in the past three years, I got very frustrated when I failed to solve the problems and questions.
