Soo tired at age 17 you should be full of energy.. re-charge your battery and get your ass into gear hahahaha
I understand about difficult learning & sciences, at school I studied physics as my compulsory science subject very hard !!!
Then I finished school at age 16 I started training at an aircraft company as an intern for 5 years, (age 16 to 21) studying aeronautical engineering, working Monday to Friday at the company & attending University every Saturday.. 5 years to get my Masters degree certificate... Phewwww nuay mak mak !!!
But after that I was a certified aircraft flight engineer which gave me work all my lifetime !!
So study hard now & enjoy a good life later !!!!
If you think your English is worse than my Thai.. just wait until you hear me try to speak !!! hahahaha
My sound must be very bad 55555
