Computers is the subject most parents cannot help with at home. A maths sum can be checked at the kitchen table; a program that will not run cannot. It is assessed differently too, with practicals and projects carrying marks alongside the written paper, so the work has to actually run rather than simply be remembered correctly.
The other difficulty is that the subject means different things in different schools. One syllabus teaches Python, another Java, another spreadsheets, databases and web pages, and the Class 11 and 12 computer science course is a long way from what the same word covers in Class 6. It is worth asking a tutor what they have taught before agreeing anything. Sessions here work best at a keyboard, with the student typing and the tutor watching the error appear, because debugging is the real skill and it cannot be learned from notes.
