The main concern was him completing his work. But I think if he was more confident in his writing and comprehension, he would complete his work.

The area of greatest concern is his writing. His handwriting is kindergarten level with a lot of kindergarten level misspellings.

Well, he's back in school now. In that case, would unschooling still be effective?

I pulled my child out of school in the 2nd grade and decided to homeschool him. All three years, I was having a psychotic episode. He learned almost nothing and the learning loss is monumental. How do I fix what has been broken? He doesn't know how to learn anymore.
