Medium-level Data Sufficiency questions in the two-statement format, where you judge whether statement I, statement II or both settle the answer, each with a worked solution.
Beginner data sufficiency practice where you decide whether statements I and II are enough to answer a reasoning question, with a worked solution for every question.
Beginner input-output reasoning practice on word, number and mixed arrangement machines, vowel-based word ordering, letter rearrangement within words and tracking positions across steps.
Hard inequality practice on long chains, worded, symbol and Greek-letter codes, and conditions where one relation must hold while another is definitely false.
Medium-level coded and direct inequalities practice on symbol, word and Greek-letter codes, statement-conclusion questions and filling blanks so a required relation holds definitely.
Hard probability problems on conditional events, binomial trials, bag transfers, turn-based draws and multi-card combinations, each with a step-by-step worked solution.
Medium-level probability on overlapping events, complements, combination-based ball draws and independent shooters, with card, dice and coin problems that need careful counting and a worked solution for each.
Basic probability practice on coins, dice, playing cards and coloured balls, covering complements, independent events and draws with and without replacement, each with a worked solution.
Advanced statistics problems on grouped mean and mode, corrected averages, missing frequencies, rescaled scores, coefficient of variation and standard deviation, each solved step by step.
Medium-level statistics practice on combined and corrected means, median from frequency tables, missing frequencies, the empirical relation, coefficient of range and standard deviation.
Easy statistics practice on mean, median, mode and range, correcting a wrongly recorded value, the empirical relation and how scaling data changes variance and standard deviation.
