About this course
Contest problems reward clear thinking under a time limit. Learners often know many algorithms but lose time on slow input, wrong complexity estimates, off-by-one mistakes and edge cases, or they do not recognise which technique a problem is hinting at.
This course covers the standard contest toolkit: reading constraints to choose an approach, fast input and output, complexity estimation, binary search on the answer, two pointers and sliding window, prefix sums, sorting and greedy methods, recursion and backtracking, bit manipulation and number theory, graph algorithms, dynamic programming, and advanced structures such as segment trees.
Train on your own with our free coding challenges and pattern lessons, or work with an affordable 1:1 coach who reviews your solutions and helps you build a practice routine.

We will suggest a plan that fits your budget and flexible timings in your time zone, and you can start this week.

How it works
Four simple steps to start Competitive Programming with a mentor. A real person replies to you; there is no booking system.
Message us on WhatsApp or email, or fill in the short form. The first chat is free, with no obligation.
We listen to your goal, level and deadlines, then suggest a plan that fits your budget and timings.
Online 1:1 sessions with a mentor who knows your course, explains clearly and checks your understanding.
Keep going between sessions with practice, and watch your confidence grow week by week.
Learn by doing
Build a reusable template with fast input, helper functions and a test script, and keep improving it as you practise.
Run a timed set of problems each week, then write a short review of what you missed and the technique it needed.
Collect five solved problems for each major pattern, with the key insight written in one sentence for each.
Write a small script that generates random inputs and compares a fast solution against a slow, simple one to catch wrong answers.
