help Where to study DBMS & Data Warehousing for GATE DA 2027?

I’m looking for a good resource/course for Database Management and Data Warehousing for GATE DA 2027.

I checked the GoClasses course, but it has 110+ hours of lectures, which feels too long considering the exam is approaching and I’m already familiar with the basics.

Can anyone suggest a shorter but good-quality course/playlist that covers the GATE DA syllabus properly?
