I am moving to Coimbatore from US next year 2023. My daughter will be in 7th rade and son in 1st grade. I am looking for IGCSE for my daughter and IB syllabus for my son as they study the same here in US now. I shortlisted KSIRS for IGCSE syllabus and TIPS for IB syllabus . Is that good choice? Any other choice for both IGCSE and IB.
