in item # 23 you mention about schools, it is better to start with 12th grade. So the same should come in item #20 as last but one..the last one you can give as xcity/xstate/India till 19YY, next you give your 12th school city/state/India xmonth/19YY-ymonth/19YY+2, next give your graduation city/....., work1city....,...
I think this will help. this is how, I had given in my DS 230 P1.
