Thank you for sending me your homework. I can clearly see that this was not an easy homework for you. ;-)
You wrote a lot but you did not really answer my questions. You only had to care about the call option for this specific example and the specific questions. Instead you wrote a lot about other things and I don`t understand why.
Nevertheless I appreciate your work. For future homework please answer the right questions. It is not about quantity it is all about quality. ;-)
In the future you must learn more for your examinations so you will achieve better grades.
Try to improve your written English so in the future it will be easier for you to find a good job or to carry on with an international academic career.
There are big chances in Thailand for well-educated people. Try to work harder so you can make sure that you achieve your personal goals.
I personally wish you all the very best for your future and hope you will succeed in life in the way you want.
Best regards
Holger
