Thousands of Indian engineers take the GRE each year and a majority of them struggle with the Vocabulary section that requires them to know the contextual meanings of words not used in everyday conversations.
Wordtoons is a set of GRE flashcards designed especially for Indian GRE aspirants. Through visual cues and silly vernacular clues, they make learning fun and help the words and their meanings sticky.
I conceptualized ~150 of these flashcards and worked with an illustrator to get them created. These are offered as part of the GRE course material at CrackVerbal and also retailed on Amazon.
