 Based on his own scores that Rec0man provided, the breakdown is as follows. 0000 English score Chinese = 00.0 Indian = 00.0 Malay = 00.0 0000 Math Score Chinese = 00.0 Indian = 00.0 Malay = 00.0 Even assuming a linear relationship between test scores and IQ exists (which it doesn't) the gap between Indian-Chinese math scores is far more significant than the difference in English scores. Since there is no clear formulaic relationship, even simply assigning proportional weighting to the actual test scores yields an Indian IQ of 00.00.
