Write down your learning goals.

Hello,

Since I want to improve my English's writing, I begin with some easy topic from the "Oxford Word Skill Intermediate" but it still seems to be hard for me, so much. Please help me correct it! The words I put in italic mean I wonder if i use it appropriately. Here is my essay:

My Dad often told me that every subjects we learn in school are important and I should not just focus on one or two "main subjects" like Math, Literature (they are main subjects in Vietnam) at all, I should study history, geography,... (which are just the auxiliary subjects) well too. I definitely agree with my Dad.

My favourite subject is English, but I know if I just worked on English and had no care on the others, how would I talk of a topic with the foreigner? So my goals of learning are not only will I spend time making progress on English but I will also balance my time with other subjects.

However, go into the detail in English, I wanted to attend the speaking contest to improve my presentation's performing, body-language, and to know how to expand the topics. Then, I would like to take IELTS test.
