This DSA Self Paced course helps students to have great foundation to solve DSA in C problems. This will help them to solve LeetCode MCQ / problems and in google faang data structures and algorithms in C (DSA) MCQ / interview questions.

What students are saying about this course-

"Till now I felt Data Structures is a complex subject. But this course is helping to understand how simple they are."

"This is exactly how I hoped to learn data structure and algorithm, PLUS, it's using C!!"

"Instructor is teaching in very well and efficient manner with a good pace ,clears every doubts and teaches concepts deeply."

"Great class, explains all DSA topics very well, better than any college class I ever took."

"yes this course has helped me a lot in discovering new topics and the example programs are also quite helpful."

"I really appreciate the way the steps are broken down incrementally."

"Deepali does a great job in explaining all the concept and the course is very well organized. First the concept is explained on paper and then there is a walk through of the code, and then execution of the code. I have learnt a great deal from this course."

"I am taking notes and writing code side by side watching videos which makes it beneficial to understand the code and easier to grasp the concept of the topic rather than just copying the source code. Thank you Deepali Mam for not giving the source it was better to write the code by myself. The videos are informative, detailed and right on point with step by step code programs and I feel learned a lot taking your course then the class which I took at University. This course made my base of data structures in C pretty strong thank you for that."

"This is an awesome course. If you need to understand then try to write every code yourself then try to analyze it. that's how you can gain confidence."

"I'm re-learning something what I am learn years ago, and this course is perfect for my need."

"Its quite helpful, it nicely supplements what you have studied in the book."

"Excellent presentation and content. Easily comprehensible. Since Data Structures and Algorithms are heart of computer science will give a 5 star for this kind of knowledge resource."

"It is one of the best courses that I have ever taken in Data Structures and C."

"Good foundation course covering the fundamentals of data structures in C."

"It's definitely a good course for beginners who have basic knowledge in C and want to learn Data Structures and Algorithms. Really good explanation by the instructor with experience of even writing a book on Data structures."

"Till now its above expectations. Mam I am also following your both book "C in Depth" and "Data Structure Using C"."

"Great in depth explanations of the data structures and algorithms covered."

"good and perfect teaching for basic levels for beginners in data structures."

"Very good clarification and reference for common data structures and algorithms."

"The Course material was very good and the concepts and the logical reasons behind the algorithm is explained."

"It was a great experience"

The contents are good, but the course is very fast and the explanations are very short and could be better. (I usually I watch lectures at 1.25x - 2x speed, but here I even had to slow down to 0.7x sometimes). For me it was not a big problem, as I already had experience with C programming/DSA and just needed a refresher - won't recommend this course for beginners though. Planning to take the second part of the course (Advanced DSA in C) next

By Kshitij Garg on 12/10/2021

The course is short, crisp and filled with knowledge. I have not seen such no nonsense course like this. I took it a year back and I am revising my concepts from this course as it saves my time and concepts gets brushed up easily. Thankyou Deppali Ma'am, this course is like a hidden gem.

By Lloyd Malecaut on 11/25/2021

If you're looking for a course to learn DSA in C then look no further! I chose this course so that I could start to tackle problems on LeetCode and I can honestly say that the course fulfilled this aim. Deepali is a fantastic tutor and I have now enrolled in her course on advanced data structures and algorithms in C.

By Akshat Sabavat on 6/2/2021

This is honestly a very poorly made low developed course ,All you do is explain the simple parts of data structures its base concept but this course will not equip you for a job due to the lack of practice questions niether will you be able to code what u learned as the instructor reads the code as if it were a history lesson and expect us to understand why and how certain assignments or statements work I honestly expected more . Very disappointed. I hope you take my critisim in the right way and improve the course contents

By Davy Ronald Hermanus on 11/26/2020

great!

By SNEH AASHISH GUPTA on 11/18/2020

The teacher should include code files with each lecture and should also work on correcting the captions, this course just touches DSA and doesn't go in depth

By Dipesh pandey on 9/12/2020

teri problem nahi hai,,,,coding hi wahiyat hoti hai

By Peta Varshini reddy on 9/9/2020

i want to become a master in this course.. i hope u would help me with it

By Guruaakash on 9/7/2020

Good teaching

By Sahana N.B. on 8/15/2020

if the speaker could be more enthusiastic in conveying the topic, It would have been even better. But its a good one so far!

By Gift Chimphonda on 8/15/2020

It was a good match but the delivery is too fast. I wish had a powerpoint presentation or a book so that I could catch up.

By Shatabdi Kaushik on 8/9/2020

The course is good and most of the things are pretty much in depth but the instructions in the videos are very slow for my taste and understanding.
