My computer doesn't have Thai Keyboard but I really wanna reply this asap
1. You should start with Math,the hardest one then Physics and chemistry
If you are not the read-them-all type Biology Thai and Social should be the last.
2. No need if you can force yourself to read them. I recommend Bio P'Tent and Doc aptitude of the Book publishing
3. Me,too! Definitely, do lots of practice tests cause you might not understand some questions,seriously.
4. With pleasure

5. It's a big problem when you take aptitude test though

Fighto
6. None (offense) taken
ึ7. Well, I want you to think about it REAL HARD. It's a though choice that change your life and it's a one way street
They are not forcing you but still you feel the pressure, right? And most of it comes from yourself
Like the last reply said, you can build the hospital for them instead of being a doctor.
You don't have to be a doctor to help people.

If you are doing this to fulfill a duty of a good son, what if you hate studying medicine?
Are you such a good son that you would sacrifice your whole life as your parents wish?
Is making them proud more important than living your life?
Key question; what is more important to you; - your own life or your parents' dream
Just choose what you won't regret
