Gender exceptions.
I'm a bit confused about el/la... I know that EL is used when a word ends with -o & -ema. then LA, for the words ending in -a & -ion. But how can we know if a word is an exception??

The exceptions are memorised, there isn't one single and reliable way to judge if the gender of a word is one of those special cases.
But there's some good news! Firstly, the exceptions aren't really that many and you'll remember most of them before you even notice. And secondly, in the majority of cases getting the gender wrong doesn't really matter all that much - chances are you'll still be understood.
