Live Interactive Course


    You can attend a free demo class from your mentor before joining the course. This session will go around 90 min of duration. You can clarify all your doubts during this live demo session before joining the batch.

    We offer fully online classes via live sessions due to the outbreak. That means you can talk to your instructor in real-time, just like a traditional face-to-face session. Additionally, at this time, all practical sessions of our data structures, algorithms & problem solving course will be conducted using cloud-based services.

Firstly, we offer live online classes for our Data Structures, Algorithms & Problem solving course. Also, all of our students have access to recorded versions of those classes. In addition, we also give you unlimited access to these recorded sessions, so you can go back to them whenever you need theoretical help for your interview preparation. As a result, you need not be disappointed if you miss any of the live classes under our online training. However, we strongly advise you to participate in all live classes.

Most importantly, if you do not understand an entire module under the DSA live course, you can repeat the same class with another batch. Thus, leaving no chance for you to remain in confusion about the learning modules.

After completion of the demo class, we offer 15% early bird discount for the next 10 days. If you join within 10 days after the demo class, you will be eligible for a discount.
