Course Content Missing



Dear Sir,

While going though the Course contents for ‘CCA 175 Spark and Hadoop Developer – Python’ from the link - all the contents are missing form Course Content 5 (data analysis), 6 (streaming analytics)and 7 (Exercise). However content exists for 1 - 4. Could you please let mw know if 5 to 7 contents are part of of premium contents that we need to purchase ?
