How difficult is to be accepted as an international Undergraduate student in University of Warsaw?

Hello, I would some help to know how difficult is to be accepted as an international Undergraduate student in University of Warsaw?
The programmes that I saw where taught in English, based on my information do you guys think that I can be accepted in this university? Is there anything that I can do to raise my chances?

How is the reputation of University of Warsaw in Poland and in Europe

Some information:
My High school Gpa 2.71 (b-) (In the American system of grades)
I study in a good Business University here in Brazil and my gpa is 9.0 ( the maximum is 10,0)
I am learning German and I will take the Testdaf (test to show your level in German) next year
I know Portuguese ( my native Language), English (My toefl ibt score was 110) and Spanish advanced
I have been working for 1 year now
I started to learn Polish last month
Thanks in advance

Why, exactly, do you want to study in Poland, of all places? Frankly, I would be wary of any program taught in English in Poland. They are generally of poor quality, and the diploma you get might not be worth much on the job market.

What, exactly, do you want to study?

I assume the majority of foreign student who choose Poland do so out of economic society. The foreign students in the UK, comprise of wealthy Russians and Chinese. Same goes for other European countries cost of living.

1000 Brazilian real gets about £250 Sterling
1000 Brazilian Real gets about 1270 Zloty

Conclusion 1270 Zloty in Poland goes further than £250 in the UK. So if you are a foreign student on a tight budget, Poland is the cheapest European country to study in.

I expect living costs in Brazil are comparable or cheaper. Plus there are lots of other universities in South and Central America where that would also be the case. The question was why, specifically, Poland? Poland is far from an exception as far as living costs are concerned, so that is not a valid reason.

Plus the cost of the courses is much less and they are much easier to get a place on.

It's quite possible, that in spite of the reduced costs, the degree will not be worth the investment. English language programs at Polish universities tend not to have a good reputation.

The OP is a serious student, and would probably be better off studying at home in Brazil, or in another South or Central American country. They may also be eligible for scholarships to study in the States or in another English speaking country. Poland should not be at the top of this person's list, even if cost is taken into account.

I'm interested in what the OP is thinking, not what they may be thinking.

So let me repeat my questions to the OP:

What, exactly, do you want to study? And why, exactly, so you want to study it in Poland, of all places? And why not in Brazil, another South or Central American country or in an English speaking or German speaking country?
