Most likely, they will check what courses you have made in Spain, and then they may make you do some courses that you would have had in Poland but you haven't in Spain. Most of the courses at Polish universities are obligatory for the specific study programme and cannot be changed, there is a small amount of ECTS points that can be used for so called "elective courses". On the other hand, they can accept some courses that you have already had in Spain and in the Polish university they are going to take place on a higher year, and they will not have to do them in Poland.
Basically, the whole study programme, all the obligatory subjects from the Polish university has to be completed. If you have made something similar already in Spain, then they should accept it, if not, you will have to make this course extra.
You will not have to pay a tuition fee, but the number of ECTS points you can make for free is limited (it is somehow more than the "default" 30 points for a semester, but anyway it's limited). I don't know what if you exceed this limit by having to do something extra because of not having had the given subject in Spain, whether you don't have to pay for this extra. I don't think so, but you should ask the university.
Yes, provided that you can get a place on the course (which will require you to prove that your marks are the same level as other people who are admitted to that course, good luck with that) and can study in Polish (really good luck with that).
There are also study programmes in English. Yes, it may happen, that a teacher demands the students to have already had a given course before - but in such a case you should always talk to the teacher.
Generally, in such a case the university will be probably more "flexible" with respect to you than to normal students and let you make a given course later.
more than 50% at least.....they are the same as in the list of courses from my spanish university.
You should look on the study outcomes in the course description, not only at the name of the subject. But yes, the Polish university decides about that, and it's quite likely than when the names are the same, they won't even look at the descriptions... It depends on the university and on the faculty, how rigorous they are.
You'll have to contact the universities you're interested in and ask them.
Exactly. It may be even different between two faculties of a single university.
It sometimes happens that two faculties at one university have similar study programmes. Like at my university there is for example robotics and control engineering at the electronic engineering faculty and a programme with the same name at the mechanical engineering faculty, and even though the names are equal, they have a lot of differences in the subjects and their contents (one of them is focused much more at the electronic side of robotics, the other one at the mechanical part). The same is with computer science - it is at the electronic engineering faculty and at the physics and mathematics faculty, and each of them is really different (the one from the electronic engineering faculty is focused more at the hardware, the one from the mathematics faculty almost only at the software).
Hope i don't have to remake courses that i had already taken.....
It shouldn't be so. If the university makes problems with that, the thing you can else do, is just to talk to the teacher with whom you would have this subject in Poland. It might be so that he allows you not to write the exam, but he would just copy your grade from Spain, after converting it to the Polish grading system.
In Spain i only have 4 courses left but due to a change of studyplan....they will become like 10.......so......no thank you.
It might be so. It would be good to ask different universities in Poland about that, showing them your exact study programme from Spain and telling what subjects you have already made.
As far as I know, the Polish students I have studied with were paying some subsidized fees(not as much as we the non EU) if they opt to study in English.
It is sometimes so that for the studies in English it's necessary to pay something - but it's still much less than the usual tuition fee at private universities, or also at public ones in countries with no free studies. Polish law allows that, but it depends on the university.
I believe the transcript must be legalized or apostilled and in polish ? ( or english ?)
English should be accepted. The universities are dealing a lot with transcripts written in English, for example in case of Erasmus students.
By the way, if:
In Spain i only have 4 courses left
maybe Erasmus in Poland would be a good idea, instead of moving here your study? Of course, if your university offers that.
