Thanks a lot madam

From Tamilnadu - My son (9th grader) is a creative person with deep interest in tech, electronics and music. From his young age, I see him scribbling designs of various machines, it started with car designs, then robo design, laptop and now he develops good electronic projects based on Arduino. As far as competitive exams and problem solving skills are concerned he isn't natural but with practice he can do. He scores above 90% in cbse exams but I never asked to write any competitive as I felt it would pressure his creative side. Now, my question is should I put him through this competitive jee race or I opt for a Tamilnadu state board school where he has less complexity more rote learning and can get through within top 10 anna university based colleges just with his board cutoff. I am highly sceptical about jee- being a general category male student, it highly discourages me to take the gamble as it may affect his mental health. Also, after all the effort, there is a high chance that he may have to go to a deemed University based on management seats. Now my question is problem solving and competitive focus of jee and conceptual learning of cbse are going to help him anyway in the future in his workplace? I am afraid that he will lose his hobby and strength in the rat race. Kindly advice.
