I think a profile and board are completely different there though because profile/career is considered to be the same as what you said people choosing the four profiles(in my case its 3 engineer, medical(you know all the nature and animal and human studying you have to study them in one sitting if you choose this during 10th till 12th before you can choose among them in uni) and social studies also known as commerce) you mentioned and the three boards contain 6 subjects(1st to 10th) before choosing contains English(1st language), Country's language(2nd language), science(physics, chemistry and maths) (yes all three), social studies, computer science(not that important but is necessary for your school) and Maths. You are supposed to pass all of them to get a good seat in college.(11th and 12th).
Courses in college: PCMC(i chose) : Physics ,Chemistry, Maths and Computer Science
PCME: Physics, Chemistry, Maths and Electronics (by the way these two are different)
PCMB: Physics, Chemistry, Maths and Biology(there is no choosing at this time like yours)
and commerce you know only social studies and maths.
