I had the same experience when my son was in P1. He's all the time lagging behind his classmates but still I enjoyed studying with him Academic result doesn't mean everything. Most important is he enjoys school life and I always remember how lucky I am to have a lovely kid of my own.
Same like you. My daughter is in P1 and she'll finish the exam tomorrow. Then, I have to start studying with my son who is in P6.
The husband doesn't bother to study with the kids as he thinks that they can manage by themselves, like what we did when we were small. I disagree as education nowadays is so different.
