need some detail presentation will required to easy to understand logic in short time

Pujari Adarsh

It was a good first session. Looking ahead for the next session soon.

hello arun sir the class was great plz write the leet code question number before on the screen before sending the link because links are dissapered after restart

I didn’t see any issues as of now.
Thanks.

Everything from way of teaching, understand sturents , and specially your mindset is best to make us dsa expert …thanks arun sir

Bhavin

Pace and approach is proper. Able to understand the concepts (like fibonacci palindrome) clearly now. Looking forward to learn more and thrive!

Santhosh B

Arun makes a Slow and steady teaching approach which is really good. Making sure everyone understands the topic.

Subhash pal

As i am beginner in DSA, but don’t feel like it because Arun Sir making every topic so easy to understand

Maneesh Pal

Explanation of the problem is good. we should not waste our time till 12:15 to start class

Basil

– good teaching approach.starting with basic and going to advance on the same topic.
– need to clear instant doubts in session itself. pls dont tell that discuss in doubt clearing sessions.

Shivam

Good teaching approach along with problem solving . Clear explanation.

Vinod Kulkarni

Arun has knowledge and patient
Explains each concept clearly
Gives good number of examples and exercises to practice

Sharanpreet

This is a great class. Dry run is the best part which helps one understand about the code flow.
Arun interacts very well and ensure everyone is active.

Chaitanya

today i have session about reverse a number and Fibonacci, it was really a good session.

Raghav Kalia

DSA Math class 1
Approach is okay
Algo Dry runs help
While solving actual leetcode question a few extra minutes could be given not a major issue though

As this was a beginner class can’t add more inputs

Ramulu

Explained concept Cleary and also practiced problems on the same.

Manish

First session was decent, only thing that would have made this 5/5 is an overview topics and how each topic is related to other topics

Vishal

Class Was fun, was able to grasp the concepts and gradually increasing the complexity really helped in understanding the problems better.

Just a small con, can we also discuss time complexity and space complexity of each problem. as I have usually get them wrong. so understanding those with respect to each problem will be better!

arjun

plz write the leetcode question no. as due to network issue my 45 min class left and all leetcode links disappeared

Uday

The approach is good for now, may be in the later classes we might have to see if this is the right approach as this is just the beginner level class

Poonam

liking the pace and the class work

vishesh jain

good like the each question was practised in the class and going at good pace

Somasekhar

Expecting more optimal approachs to solve a problem

Rav Jain

Value for money. Worth it. Teachers are good vinamer and shubham good. Kartik dsa need to improve

Gaurabh Khugshal

Nice, would recommend it to those who wants to excel in dsa and system design.

Salar Raza

It was informative

Priyansh Jain

Very practical and good sessions, just need to improve more on individual progress status.

Bikram

Good Points
1- good explanation related to topics
2- Engaging in class

Improvements
1- Timing need to change either early morning or late evening
2- Try to handle the class topic discussion as per normal , no need to ask each and every learner for it, as its taking more time according to their experience

Ishika

This is the best course and we have the best trainer Arun, who is professional, knowledgeable and is patient enough to be with the students’ pace. He never laughs or judges students for asking even silly questions.
He teaches with Video On, which makes us more serious and alert and present in the class. He would also pay personal attention to students as possible.

Piyush is the one with whom I registered the course. He is always quick to response and act.
The course is well designed in sequence of topics to be learned first, from moving easy to difficult, from basic to advance.
Also, the fee is quite affordable. With in the same amount, they allow us to join the batch again. Their portal has myriad of courses with practice problems. This is the best course, best trainer in affordable cost with placement assistance from resume building and linked in profile. What else would learner, or an IT professional would need?

please solve the first coding question so that we learn how to code the concept.

Partha Pratima Dash

The class was good , happy with the lecture.
improvement can be done is by not entertaining candidates asking homework doubt instead of asking in doubt clearing classes . and I think we can cover more in the class if we can stop that

Arun Kumar Allepu

Course Content :-we have number theory section and math section but as i can see there are lot of problems which we can solve similarly there are problems which we not able to. like binary exponentiation we need more doubt sessions and more interactions.

SWARUP

Teaching is good. Even if any student has a very small doubt or not able to understand arun takes time to explain.

Nikesh

the class is going well and need to practice more problems during class hours use common language avoid Hindi in class hours
