Hello every one..Help is needed

I need your help in this issue.please reply

I first would like to thank you on advance for your response.

I live in Saudi Arabia and I am working in Pharmaceutical Company.
my wife lives in Saudi Arabia and she completed her secondary school in Saudi Arabia, then she is planning to complete two year diploma in one university located in other country (Yemen), I mean she is going to get diploma (two year) and not bacholrie and that will be by distance learning .university is accredited from ministry of higher education in Yemen country.

I would appreciate if you tell me about her certificate, is it going to be scored once she receive it or not.

I have submit the file to Canadian embassy with following points

Education 20
Age 10
Experience 21
Language 16
Adaptability (wife).....

I considered when I prepared the file that my score in English is 16.

My question:

is the immigration office accept the Distance learning from accredited university ?

Re evaluation for my pass score in Canadian immigration once my wife gets her certificate after one year and half (graduation for her) are possible or not. I mean; will it be acceptable to get 12 points in English instead of 16 because the 4 points will be compensated from wife certificate
