im a student and i love to learn new languages

First notebook entry: Introducing myself

i really want to learn English because I'm a student and I got less marks in english.

'Less' is wrong in this case, it should be used with uncountable nouns (sugar, petrol..) the right word is fewer. Both words are comparing with something or somebody....

'I got fewer marks than my friend.'

'He has less money than his sister.'
