It’s great that you’re planning early for your son’s JEE journey. Moving to Sri Chaitanya or Narayana in Bangalore for an integrated school + JEE program can help if he is comfortable with a structured schedule, regular tests and competitive pressure. These schools focus strongly on Maths and Science from class 9, which may boost preparation. However, if you feel he needs a balanced routine with less pressure , he can continue in Shimoga till 10th and later join a reputed coaching institute in class 11. Many students crack JEE successfully through this route too. So the decision mainly depends on your son’s comfort level and learning style. If he is motivated and ready for early intensive prep, Bangalore integrated programs will be useful. If not, staying in Shimoga is absolutely fine. All the best to your son’s future.
