1,401 past questions, classified into 155 sub-types
Most TCS prep gives every topic the same weight. This does not. Every topic below is ranked by how many questions it actually contributed across eleven past papers, a PYQ repository and two question banks.
Numerical ability
Reasoning
Numerical is the largest section and the one candidates run out of time on. Reasoning is the smallest and the one they call easy — which makes it the best marks per hour in the paper.
What you get
Grouped by topic and ordered by the same weights above, so the first thing you open is the thing worth most.
Each with a brute-force solution, an optimal one, the complexity of both, and the edge case that fails the hidden tests. All 115 solutions compile under Java 20 and pass 87 assertions.
Sentence completion has no options — you type one word. Simple Interest came up five or six times a slot. Trees and heaps are in the coding section now. Read from students who walked out and posted the same day.
A trailing space failed a whole slot on 28 June. The class name has to match. Scanner.nextInt() loses questions when the input arrives comma-separated. Documented from the people it happened to.
