    ANUNT IMPORTANT!

    Inscrierile se vor face exclusiv online , vor fi postate detalii despre aplicatia de inscriere! In functie de evolutia situatiei de criza, se vor lua decizii privind modul de desfasuarare a examenului de admitere. Toate detaliile vor fi anuntate in timp util!



    Anunturi pentru candidati, valabile daca examenul se va sustine fata in fata

    • F. IMPORTANT! Admiterea la Domeniile de licenta Matematica si Informatica va avea loc in aceeasi zi, cu aceleasi subiecte. Candidatii pot opta la inscriere atat pentru Domeniul de licenta Matematica cat si pentru Domeniul de licenta Informatica. Candidatii care se vor inscrie la Domeniul de licentă Informatica vor trata, obligatoriu, un subiect de informatica si, la alegere, unul dintre celelalte trei subiecte propuse. Vor fi anuntate mai multe detalii.

    • F. IMPORTANT! Admiterea la Domeniul de licenta Informatica, programul de studii Informatica, forma de invatamant la distanta/cu frecventa redusa, va fi organizata numai in luna septembrie. Admiterea va consta in analiza dosarului si o proba orala. Vor fi anuntate mai multe detalii.
