Computational Thinking

Computational thinking is a practical way to structure difficult problems so solutions can be reasoned about, tested, improved, and sometimes automated. 25 modules, each one a lesson plus a locked checkpoint.

What's included

01Frame and Simplify ProblemsDay 1 · 5 modules

Build the foundations of computational thinking by learning how to define problems precisely, separate inputs from outputs, identify constraints, decompose complexity, recognise reusable patterns, and create useful abstractions.

02Express Solutions with Logic and AlgorithmsDay 2 · 5 modules

Translate structured problems into precise algorithms using sequence, conditions, Boolean logic, iteration, state, data representations, traces, test cases, and correctness reasoning.

03Choose, Test, and Improve AlgorithmsDay 3 · 5 modules

Study search and sorting strategies, build reusable procedures and functions, debug systematically, and compare algorithms using efficiency, scalability, and practical trade-offs.

04Use Data, Models, Automation, and Systems ThinkingDay 4 · 5 modules

Apply computational thinking to data practices, models, simulations, automation, parallel work, dependencies, bottlenecks, feedback loops, and whole-system behaviour.

05Optimise, Govern, and Integrate Computational SolutionsDay 5 · 5 modules

Solve constrained optimisation and decision problems, design rule and scoring systems, apply computational thinking to data and AI workflows, evaluate responsible use, and complete an end-to-end capstone.

Grading system

Every module ends in a checkpoint: two questions, locked the moment you answer — no retries, no second attempts. Across 25 modules that's 50 marks. Your Learn50 Score is the percentage you get right, and it earns a Tier you can put on LinkedIn or your résumé. A Tier starts at 40% — below that, the course records every module you finished and every question you sat. The credential is real because the test was real.

Diamond90% – 100%

Platinum80% – 89%

Gold70% – 79%

Silver60% – 69%

Bronze50% – 59%

Before you take this course

English language proficiency is required to understand the teaching.
This is interactive, slide-based learning. Please take Module 1 free to check you are comfortable with the format.
Logical, step-by-step reasoning is recommended, because this course will have you decompose problems, trace algorithms by hand and compare what they cost.
This is not a programming course. No coding is required and none is taught — you will reason about algorithms, not write them.
Making notes and working through the formulas along the way is recommended.
Where examples use money, amounts are in Indian Rupees (₹).
About 30 minutes of focused learning a day, closer to an hour if you make notes. Please take the course only if you have that time.

Questions

Before you buy.

No. There is no eligibility requirement, no entrance test and no application — anyone can buy it and start. Every term is defined the first time it is used. No programming background is assumed. The first module makes the point that computational thinking is not a synonym for coding — if you have ever had to turn a messy process into clear steps somebody else could follow, you already have everything this course refers to.

No. The 5 days are a pace, not a deadline. Access is for life, so you can take 5 modules a day and finish in 5, or one a week and finish when you finish. Nothing expires and nothing is withdrawn if you stop for a month.

Every module ends in two questions worth one mark each — 50 marks across the course. Your Learn50 Score is the percentage you get right, and it earns a Tier: Copper from 40%, up to Diamond at 90% and above.

No, and that is deliberate. Each question locks the moment you answer it. If retakes were allowed, everybody would eventually score 100 and the number would mean nothing — the score is worth putting on a CV precisely because it cannot be ground upward.

At 40% and above, a certificate that is a web address rather than a file — anyone you send it to can open it and see the same score, date and certificate number that you see. Below 40% the course records that you finished every module and sat every question, marked as Attempted.

No, and it does not claim to be. It is a certificate from Learn50 recording a score on a test you sat once, with no retries. It is not accredited by any university and is not a substitute for one.

$6.00, paid once. There is no subscription, no renewal and no expiry, and no further payment at any point in the course. Every Learn50 course is priced at the same rate per module, so a shorter course costs proportionally less rather than more.

Yes — a full refund within 7 days of purchase, or until you complete the course, whichever comes first. Completing the course means finishing every module, at which point the certificate has been issued and the refund window closes.
