Regarding form filling for FSW Education Section

[scorpio77]

Dear Friends
There is a column in this form under point 7 for Education Section
Give the number of years of school you successfully completed for each of the following levels of education
Elementary/Primary School. Q. Primary school is up to class 5 level or till class 10th or till class 12th. . So answer should be 5 or 0 or 12?

Secondary/high school: I am assuming this should be class 12th. So answer should be 12?

University/College: This should be the total number of years spent on degree + masters? In my case I have done 3 years regular diploma(electronics & commn engg)+ completed AMIE(equivalent to BE in distance learning mode in 5 yrs in parallel with Diploma) + M.Tech (regular) in 2 years.
So accordingly this should be 12(till class 12th)+5(AMIE)+ 2(MTech) = 19 years. or I should count only full time education 12(class 12h) + 3(full time diploma) + 2(MTech) = 17.
Or I should just write 12 + 5 (AMIE equivalent to degree)

Trade School or other post secondary school: Not sure what should I fill in this?

Thanks in Advance..
