it could be learning something else along with X1 & XII Bi-focal courses are part of the science stream where students can opt for any vocational subject in lieu of the second language, geography and Biology. The vocational subjects include computer science; electronics; mechanical and electrical maintenance; scooter and motorcycle repair and civil engineering.
Usually, students aiming for engineering degree studies opt for bi-focal courses as it gives them better scoring opportunities. This can be gauged from the fact that bi-focal stream students have traditionally dominated the toppers in the higher secondary certificate (HSC, class XII) exams at state as well as divisional levels. Electronics and computer science rank among the most sought-after bi-focal courses.

Bifocal
it has two section,one for distant another for close vision
It means you are using a bifocal contact lens that has a bifocal power of about +1.25 to +1.50. A high add would have the bifocal power of about +2.50.

bi means 2 as in bicycle (2 wheels), bifocal (2 eyes), bilingual (2 languages).
The root word in bifocal is "focal," which refers to the point at which light rays converge after passing through a lens. The prefix "bi-" in bifocal means two, indicating that bifocals have two distinct areas for different vision correction needs.
The prefix "bi" means "2" bilateral bifocal bifurcate
Bifocals are a type of eyeglass that has two different sections of its lens, so that you can look through one section to better see close objects, and the other section to better see more distant objects. Bifocal science would be the theoretical basis for the manufacture of bifocals.
My gran has some bifocal glasses.
bifocals are glass lens that you place upon your nose & push up. they help you see better & / read
Bifocal subjects are vocational subjects. They include Computer Science, Electronics, Scooter Motor Mechanics, Electrical and Civil Mechanics. You can choose a vocational subject in 11th std as as optional subject given that you have the required percentage. Choosing a vocational subject rids the student of two other option subjects like biology, german, sanskrit, geography.
