Other comments and second exam session

L'avaluació es farà en base a la teoria i les pràctiques.

Hi haurà 2 parcials, alliberadors, de teoria

a) el primer sobre els circuits afreqüència de línea,

b) el segon sobre electrònica de potència en alta freqüència.

Cada parcial val un 37.5% de la nota final. Els parcials són alliberadors de matèria, i fan mitja per obtenir la nota final de teoria si la nota de cadascun supera els 4 punts, sobre 10. La teoria no es considera aprovada, si la mitja dels dos parcials no excedeix 5 punts sobre 10.

Cal aprovar la teoria i alliberar/aprovar les pràctiques per separat, per obtenir la nota final del curs. Això vol dir,en el cas de la teoria superar els 5 punts sobre 10. En el cas de les pràctiques, es consideren aprovades a partir de 5 punts sobre 10, i alliberades per a fer mitja amb la teoria a partir de 4 punts sobre 10.

En fer mitja amb la teoria, les pràctiques pesen un 25%, i l'assignatura no es considera aprovada, si la mitja de teoria i pràctiques no supera els 5 punts. No hi han excepcions. Les pràctiques es fan quan toca, durant el curs. No es poden concentrar. El professor de pràctiques encarregar treballs i pot realitzar exàmens per avaluar-ne el seu aprofitament.

SEGONA CONVOCATÒRIA. L'alumne es podrà presentar només dels parcials suspesos. L'alumne no es podrà presentar dels parcials aprovats per pujar nota. En cas de no aprovar els dos parcials per separat després de la segona convocatòria, es considera que l'assignatura està suspesa.
