Careless!A lesson learnt!

Today, having test early in the morning, I go all out fully prepare with prayer. I asked God to allow me to experience Him and guess what something happen??
The test is so easy that I carelessly write a wrong formula, I know I been looking and checking through, I found the answer to be weird but I just couldn't find what's wrong with it!Then time out, I realized I made mistake by putting the wrong formula. Then I was sad for the whole day, wondering can I still get an A for my physics?I'm too sad for it. Then while thinking, this thought came to my mind. I need to give praise to God for whatever it is. I still need to praise God, not blame....

Even though this experience cost a lots of mark, but I believe I still can get an A for my physics.

From this, I learnt:

1. To give praise to God, no point blaming. Still can praise God because result out will not affect much on my finals. I remember last semester, I still get an A for my Calculus even though I did badly for the first 2 test. I believe as long as I continue to work hard and learn from my mistake, final is just at my fingertips!
2. To check the consistency of the units. I believe just now exam I didn't really check the consistency of units put in the equation and then the answer. Even though I check few time but I assume that the formula is right. Substitute value should also substitute the units for the value. I'll remember this!

This lesson learnt is a bit pain and costly for me but you won't learn something unless you experience the pain of it. I want to thank God for giving this opportunity to learn a big lesson and that I will not make the same mistake in the finals which carry lots of marks.
