Which Mississauga french immersion school has higher probability of admission ?

I chanced upon this thread and thought of adding my query here since this thread is sticky and may benefit other readers also.

a. What's the difference between

IBT (Business & Technology) ,
IB (International baccalaureate ) ,
AP ( Advanced Placement)


b. Which grade do these programs start in ?

c. Do all the school boards (TDSB , Peel , York) offer their variant of the above OR these are offered only in specific Boards ?

d. I think all schools do not offer all programs .. Some offer one , some others the other .. Is this correct ?

e. Admission to a school to a said program ~ Is it based on the neighborhood & proximity OR is there any test for admission through which other neighborhood kids can also join ?

I was reviewing Khalsa School Malton- is this a very religious school. we are not sikh, but liked the principles behind this school.
