It sounds like the DS Institute provides a comprehensive study material package for students, including in-theory solved examples, unsolved exercises, and past year problems with solutions. They also offer advanced level problems for students who want to challenge themselves.

The institute follows a pattern-proof teaching methodology and keeps their batch sizes limited to facilitate proper student-faculty interaction. They offer morning and evening sessions in air-conditioned classrooms with high-quality audio and video devices.

To help students build their concepts, the institute provides topic-wise booklets with different exercises and conceptual, tricky, and brain-storming questions. They also conduct periodic tests and board pattern tests to give students ample practice and self-evaluation opportunities.

The institute offers doubt removal classes after completion of each topic to ensure complete preparation and strengthen students fundamentals. Optional competitive aptitude sessions are also available to enhance learning and prepare students for the highest level of achievement at the school level.
