How to reapply for undergraduate course after immigrating to Canada?

I will answer your question now; You said, "I immigrated to Canada with a bachelor's degree in mechanical engineering. I plan to apply for an undergraduate degree in chemical engineering at a university after I go there. I have a few questions to ask. " There is something wrong with these words?

First, you said "1". It has been 10 years since I graduated from high school. Can I still apply for my high school grades, HKCEE scores and college entrance examination scores?

This question can accurately tell you "yes". No problem.

Second, you said "2, IELTS 7. The results of the college entrance examination have just passed one line, mathematics 136, physical chemistry 120+, and other subjects have just passed. HKCEE is excellent in math and physics, but not so good in other subjects. Can such conditions be applied to a school in TOP5?

Your grades are very good! In particular, your IELTS score of 7 is very good for an immigrant or an applicant studying abroad! Others are also possible.

3. You said, "3. If I get a maple leaf card after landing in Canada and then apply, can I be considered a Canadian student, although I use my domestic high school grades? Because then you don't have to take part in the highly competitive single-plank bridge for international students. The problem is this: if you are a new immigrant to Canada, there will be no problem of "international students". If you have China's high school diploma and IELTS score, you can apply to your favorite university.

4. You said, "4. I studied a chemistry undergraduate course in China before and didn't graduate. Can I get the credits I have already completed and apply for exemption from the exam after getting the Tsinghua academic certification? It would be a pity if China's grades can't be counted as "credits" abroad without graduation!
