Sweetie, Alex sounds like a great kid who is just not a great student! I hope you know I was just teasin' ya about his nick name

maybe Responsible is a good new one
Anywho.....it is so easy for parent and kids to blur the line between kid and student. They just do not all learn the same way. School is hard for many smart kids, for many different reasons.
I told you already a little bit about my son, who can't stand school. I also have a 19 yr old, 16 yr old and 7 yr old. My 19 yr old always struggled
By the middle of 10th grade we pulled her out pf traditional school and put her into a charter work from home type of school. One teacher, one subject at a time. She busted out her work no problem. No more 'lost' assignments, no more 'I forgot'.....she just got it done. The reason we pulled her out of traditional school was that she was spiraling. Her self esteem was in the toilet....everyday her teachers told her she sucked (more or less) all of her friends were doing well in school and of course there was friction at home. I knew we had to rescue her before she ended up in the wrong crowd looking for trouble.
She graduated on time and is attending community college and doing well. She is responsible and has held a job at the same place since she was 15 1/2.
BTW....my other two DDs, 16 & 7, do fantastic in school. They just happen to fit the mold
The lesson here is the student and the child can happily blend into one, but at the same time if the education does not suit the child's learning style, then the 'bad' student can overshadow the 'good' child!
Hugs, I am always happy to hear when someone finds something that works for their struggling student!
