Step1
First sheet of paper, you need to figure out the experience that has found challenging. Write "An experience I found Challenging" on top of your sheet of paper.
Step2
For an example, write the topic "Passing High School Math" and number your paper from 1 to 5.
Step3
Number 1 should be "Introduction", #2 should be "reason 1", #3 should be "reason 2", #4 should be "reason 3", and #5 should be "Conclusion".
Step4
Skip #1 and go to #2 through #4, figure out 3 points that you have experienced about the topic. For an example, point 1 (Maybe the teacher), point 2 (Maybe the subject) and point 3 (Maybe I've didn't studied hard).
Step5
Each one of these points should match each one of these reasons about your topic.
Step6
Now go back to #1 (Introduction), you wanted to say for an example; I always have some "experiment problems" every since I was in the 10th grade, this is my first time taking Algebra 1 during the first semester. Then, write about what they should learn about the topic, that means the "Main Idea of the Topic".
Step7
Conclusion is like telling how do you feel about the experience you have taken. For an example, just use the words in your sentence (Hope or Glad and Good, Bad, or Terrible).
Step8
Now, use another blank sheet of paper and you're ready to make your essay. Write your title on top of your paper, skip one space and make two sentences using introduction, one should be what are your problems about the experience and another should be what would they learn about the experience of the topic. Do not number, it is an essay.
Step9
Use the other sheet you have already taking your notes on. Reason 1; write a sentence about the teacher and what did they do or did not do, reason 2; write a sentence about the subject you took and how do you feel about it, reason 3; write a sentence about why you did or did not studied hard.
Step10
Write an conclusion sentence, give them a "comment" about what it will happen in your entire life or anything else.
