Hello my edits and suggestions are below:
No One can not achieve victory without facing any challenges at any point( in their lives). Life is full of challenges. I have faced many challenges in my life. Sometimes I have failed, and sometimes I have achieved success. I learnt learned from (my) mistakes and it gives me experiences ( allows me) to face the next challenges. I was in year (two), when school started toget got tough. I had to learn to learning to adapt to a new place( what place? School? please specify:)), meet new people(,) and learn new skills in a short period of time.
I had decided to join a CCA despite having to juggle with my busy schedule. I wanted to meet new people, adapt to different environment, solve a problem(s), (and) accept responsibilities for a problem and solving it. However, things it started to get tough. My grades dropped drastically. ( Add here why your grades started to drop)Getting a GPA lesser than three was a disaster for me. as I wanted to further my studies which requires a good GPA. Then, I knew I was not ready for something new . I( started to) blame myself for everything. Despite all of these this, I managed to pull myself back together. A friend once told me, "No matter how bad something is, something good will always come out of it". I then realized that trying that joining the CCA which was something new, was not a bad thing.
The CCA I joined was a blessing in disguise. The new friends I made gave me advice and support, that ( this) gave me strength to overcome any obstacles. The challenges I faced were a tough one. But, slowly, I managed to pull through. My GPA got better but my cumulative GPA was not that good. I believe that a consistent or better GPA shows a student effort throughout his studies. The reason why I take This is as my greatest achievement is because in my opinion it is not just an achievement , but (also) something that changed my whole character and personality. In the end I became more confident in accepting new challenges.
Hi!
Great start! I took out some words to help you out, I see you faced many great challenges and succeeded! Try to section off your paragraphs to separate your topics. I would love for you to be a little more specific with what new place you had to adapt to and why your grades started to drop.
Good Luck!
