How are IQ level of Student and Study Techniques related

We find children with different IQ levels and different abilities. Two children of the same mother are born different. No two fingers are alike. The technique which works well for an average student doesn’t give good results for an above-average student.

For example, computerized mind maps work well with a certain group of students, but fail to produce the desired results in another group unless the methodology to prepare, study and revise the maps is changed.
