It has cbse important questions section within each subject and also has summary of each chapter (though some like physics are copy paste from ncert). It has video lectures on all topics. There are some online tests and past papers of different schools and board for your reference. Plus this discussion forum. Ncert solutions are also given. The recent feature is cbse value based questions.
