hi,

see In india right now education system is changing and computer science are adding to the school syllabus , so students of 6th or 7th grade are now get some introductory course in programming. however till now there is many schools there is no option to take computer science as option in 12th course studies. so you would learn that around 90% of students enrolled for cse in college or in graduation course has no coding experience.

once they get admission in colleges, students learn from faculty and lectures and gradually start practicing coding. so if you basic maths concept is clear you would face no issue to study programming.

so dont afraid and prepare for your upcoming entrance test.
