Iam glad to see everyone is always ready to help each other on this forum.
I have also come up with some explanation.
Iam using Ranja's and Lucky's topic and just expanding it.
This applies only if she took History in BA which i guess she did because that is the requirement for MA history if i am not wrong.
Que.1- Why she changed courses?
Ans.1- She always wanted to do something in History like MA History to become teacher/professor of History.
a. WHY TOOK BA?
So she started with BA in which History was included.
b. WHY TOOK COMPUTER?
Because of high demand of Computer/technical jobs in Canada she changed her field of study into Computers.
c. WHY TOOK MA ENGLISH?
Because she was suggested by her family members in Canada to take Engish because English is Canada's first language and she could do lots in English.
d. WHY TOOK MA HISORY?
Because she was always intrested in History and as mentioned above she always wanted to become teacher or professor in History. so she decided to pursue her studies in History rather than Masters in course like English in which she failed twice and in which she could not show her best. So her family also agreed with her decision and let her do what she wanted from the very beginning.
Also Member39 if you can get original letters from her English professors that she tried her best to accomplish MA English but she could not do well that's why they(Professor) suggested her to do what she is good in instead of something she is just doing for others. (I know sometimes our teachers/professors suggest us to move on to something we are best at)
Also if you are going to use that point that she always wanted to become History Teacher. and she is really good in History. If she is good in History thats awesome if not please tell her to study hard in history, revise her whole course from beginning as CIC can call her for Interview & ask History related Questions as we read in link that Lucky provided. Tell her to study as if she is going for Provincial exam/Board exam.
Also as Raj said you can post your Letter here and everyone can help you to make sure its good enough to prove your point.
Lucky, User, Raj, Ranja and everyone else please comment and do correct me if i have said anything wrong and also share your opinions. Even if my whole point is wrong, correct me.
