Nam are you really a poor student or do you just not understand the subject matter?
You DON"T Have To Be A Poor Student!!!! Believe Me!!!!
Being raised the way I was and often being told I wouldn't amount to a big rat's ass by the time I got into high school I was behind, didn't understand the subject matter, and was basically just a big dumb assed kid more interested in the girls and what I could get from them than I was in school work anyway.
I was also in 24 states by the time I was 13, the old man was an outlaw and didn't give a sh-it whether I got an education or not.:grumpy:
I flunked 10th grade English because I didn't have the background I needed and was having to take it over in the 11th grade.
My 1 year younger than I girlfriend missed a period and thought she was pregnant.
Back then, 1957, you did the right thing and got married, that is unless your family had money and could buy you out.
But this girl was the love of my life so we married. If she wasn't pregnant when we married she was damned sure pregnant soon after!

I dropped out of school to go to work. Worst mistake I ever made in my life!!!!
Our marriage lasted 7 years but that's another story, but the lack of education had a huge bearing on it.
Anyway the reason I'm telling you this is because if you need help find a tutor and study, study, study!
If it's just because you're being lazy buckle down, suck it up and get with the program!
Talk to your parents about your troubles if you can, if not talk with some other adult you can trust and that can be a real mentor and guide you in the right direction.
Really, someone will be more than willing to help you out! If you were nearby I would do what I could.
The main thing is to get the absolute BEST EDUCATION you can get and that starts with public schools.
Believe me that when a youngen talks to a teacher sincerely and shows that they will hold up their end of a bargain the teacher will bend over backwards to help.
If they don't then they shouldn't be in the profession.

Find another one who will help!
When I was 54 and out from work rehabing from my 2nd and then 3rd back surgery I enrolled to get my GED. I wanted the Gold and went for it.
I discovered that all the things I hated in school could be fun since I had grown up.
I discovered many things about myself, one being that I had a real horrible reading comprehension problem, a lot of it due to my upbringing.
I figured out that my viewpoint was different than other people's and what they might find funny I found tragic so I started telling them the answers they wanted to hear instead of what I thought and it worked!
I still sucked at math so I got myself a tutor and I did what I'm advising you to do!
I passed the test with flying colors and was elected to the National Adult Education Honor Society!
Only about 3% of the people that go for a GED get that honor.
I won a 2 year scholarship at our local Jr College.
I found out that I could of been many things instead of having to work at an ass breaking job that finally done me in medically and it pissed me off!
But I'm fine. I always said that if I could just help one person keep from killing themselves, save a marriage, change someone's mind about life and that indeed it is really, really worth living, then I would have done what I was put here for.
Nam, I'm a very rich man although we sometimes struggle to pay our bills because we're waiting on the next check to come in.
I have done all these things and more and more than once. Just the other day a young lady living in Northern Cal called and thanked me for all I had done to steer her right and that she often passed on the words I had given her to others.
Those things make me proud.
Just goes to show a person that they don't have to be strong and get around well to make a huge difference in helping someone better their life.
I just wish someone had talked to me when I was young, they could've maybe made a difference.
Believe me, there's help out there if you need it, find it and don't settle for being a "poor student." You're much more talented than that and I know that from the way you write and think.
