I literally just started working here and they evaluated my level of English with an oral examination, and the teacher said the next step was to take a written quiz, which she would use to sort of "categorize me" and place me in one of her classes.
I don't remember being told whether this was compulsory or not, but I really really don't want to take English lessons, for a number of reasons:
I studied English during my entire childhood, I'd hate having to study it again.
I've taken and passed several exams with good grades. I told our teacher, but she didn't know the specific exam I took (jeez..)
(Most important reason) Taking classes will mean I have to make up for the lost time (1 or 2 hours per week). I work 9am to 6pm and have a 1hr 30' commute.
The only argument against not taking classes is that while I think my written English is good, my oral English is a bit rusty. Oral English is important because of the daily standups with the remote team, but I honestly believe that taking classes wouldn't improve this; I just need to practice.
Now, I don't know how to or even if I should ask whether these classes are mandatory. I don't want to give the impression that I don't care to improve (I do) but I loathe the idea of staying after hours to make up for the time.
Also, if I ask someone, should it be to HR or to the teacher?
I am also afraid that this will escalate to the top-level managers (it's a small company) and that my refusal would create a negative impression right from the start.
