Ca inter new syllabus

At present no limit.

Study Scheme/Course Structure is revised after 10 years generally.

So, it will go on till another scheme is launched and this one gets phased out. Like old syllabus IPCC will be having their last attempt in the upcoming exams.

But don't think about such stuff. Nobody thought like that in school/college but here the thinking just changes completely. Let it be an exam only. Don't make it an attempt where one just tries only. Study, pass and move.
