mam please make the courses also in english.......
hi riya.....ur classes n techniques r just awesme.....i tried solving previous years papers using ur techniques and believe me i got all of dem right
Please make videos on all verbal reasoning like analytical reasoning (clocks, parandoms,, blood relations, ranking test, seating arrangements) logical reasoning (sets, logical Venn diagrams, statement ordinance syllogism, decision making, dices). Data interpretation, data analysis, data sufficiency ..

4. What is Reverse Syllogisms? In Reverse Syllogism, as the name suggest, Conclusions will be given and we have to find the appropriate statements which satisfies the conclusions (e.g. The conclusion that all dogs have four legs holds true, using the following two statements: (i) all dogs are animals, () all animals have four legs;)
