After DSA, core computer science is what fresher interviews spend the most time on — and it is where memorised definitions fall apart fastest. This track covers the two areas that come up in nearly every round, and does it by explaining mechanisms rather than listing terms, because that is what survives a follow-up question.
Syllabus
Built to make it stick
Read one idea at a time
Short lessons you can finish in one sitting, in the order the ideas actually build on each other.
Practise the pattern
Every lesson ends with problems tagged by pattern, so you learn the idea and not just the example.
Prove it under pressure
A timed quiz on every topic, and a mock interview when you are ready. Recall is the only test that counts.
