IMP TIP

u can really improve ur DI skills by solving puzzles like sudoku in newspaper.
and also work on calculation skills like

58*18=?
can solved in a easy way without pen or pencil (ie in mind only)
(60-2)(20-2)=

ie in 4 simple steps
60*20=1200
-20*2=-40
-60*2=-120
2*2=4
----------------
1044
and the total is 1044 ( just 3 - 4 SECOND calculation u see)
