Ankit Verma

honestly, this is the best java course i’ve taken. Deepak sir makes each topic super simple to understand. DSA part is also very well explained

Priya Thakur

The way Deepak sir explains from scratch is amazing, even a non-CS student like me could follow everything. thanks a lot sir 😊

Rajat Mehra

Classes are practical and interactive. I used to fear DSA but now I'm confident in arrays, linked lists, etc. Great teaching sir!

Sneha Kapoor

I joined with zero knowledge of programming. Now I can write Java code and solve DSA questions. Thank you Deepak sir 🙏

Mohit Yadav

Deepak sir is too good at teaching core java. his real-world examples helped me understand concepts very easily.

Harshita Sharma

superb explanation, detailed notes and practice questions provided after class, helped a lot in building logic for DSA.

Rohit Bansal

Was struggling with Java basics before. After joining this, I feel confident in OOPs, loops, recursion and more. Very good course 👌

Isha Arora

Well structured syllabus, timely classes and doubt solving is also great. Highly recommended for beginners and college students

Kunal Patel

Thank u sir for helping me build my logic from 0 level. Because of your java+dsa classes, I cracked multiple coding rounds.

Megha Rathi

No fancy editing, just pure teaching! Simple language, step-by-step flow and real practice is what makes this course awesome!

Adithya

TEACHING AND EXPLANATION ARE FANTASTIC, THE TOTAL PSYCHOLOGY AND CHARACTERISTICS OF JAVA ARE EXPLAINED. NO ONE CAN BEAT THIS TEACHING. NOOK AND CORNER OF THE CONCEPTS ARE EXPLAINED. EXPECTING SOME MORE COURSES FROM YOU FOR DATA STRUCTURES AND ALGORITHMS AND PYTHON ALSO....

Jatin Sharma

I never found this kind of pure basic explanation on the Internet of each point, exceptionally well. Being a Non-CS Student I understood everything from Zero. The beauty of the explanation is that i don't need to search often for small things on the Internet which I used to do often woth other paid courses and on the Youtube, everything is so cleared.
