A foreigner who is dissatisfied with the decision of the Voivode may appeal to the Head of the Office for Foreigners (UdsC) in Warsaw, via the Voivode who issued the decision. A written appeal should be filed within 14 days of the date of receipt of the decision.
The foreigner may file an appeal against the decision of the Head of the Office for Foreigners in an administrative court within 30 days of the date of receipt of the decision.
Important: filing an appeal in an administrative court does not legalise the stay. This means that unless the foreigner has another valid document authorising them to stay in Poland, they should leave Poland.
You have to fix every shortcomings and mistakes which were demonstrated in the refusal letter. If the major issue was the translation, go to another sworn translator and notary one more time.
Attach to the appeal the proof of paid tuition fees, it's important.
And remember about the deadline of your legal stay in Poland...
