I'm alarmed by the inappropriate verb tenses and missing words in this essay. I wonder are these the result of sloppy editing or lack of knowledge. Remember, CBEST is for
educators.
Bad memories should not be treated as a hindrance but as a learning opportunity.
"Memories" is plural. So, you should have said "hindrances" and "learning opportunities."
There are many life events that have made me realize the importance of past.
There should be a "the" before "past"
In school I was among bright and hardworking students who always top the list, but once in grade seven my grades were not good.
There should be a comma after "school" and a "the" before "bright;" "top" should be "topped."
I was so sad and depressed, my elder sister who knew all about it advise me to analyze all the mistakes and weaknesses that I have in those subjects, and work on the areas that need improvement.
The first comma should be a semi-colon. "Advise" should be "advised."
Later I found out that was the right approach, my grades went up and I was again on top students list.
The comma should be a semi-colon. "on top students list" should be "on the list of top students."
& etc. & etc.
