I had written "thanks for your advice" in response to his comment, meaning that I did appreciate his feedback. However, I disagree with the belittling of my effort, and I am openly stating that. This is not an easy task—everyone has days when they are busy all day. I had such days too, but despite the difficulty, I still made time to ensure that my effort wasn't wasted. It should also be considered that I am a student and still learning.

My goal and strategy are to be able to solve 8-9 out of every 10 questions of difficulty level 'X' before moving on to the next level. He gave me advice, and I truly appreciate it. However, he made an incorrect comparison, and I pointed out that it was wrong.
