Hi Denis,

This is very well written.  Just double check your tenses agree when you write your next notebook entry.  Because you have written 'At first' at the beginning of the sentence, the rest of the sentence needs to be in the past tense.  If you had written 'Firstly,' then you could have continued with the present tense.

Corrections:

 At first, I watched an episode with subtitles, write wrote down unknown words and learned them. Next, I watched the episode with the turned subtiles on.subtitles turned off.  I  noticed that my listening skills became much better, moreover, my vocabulary has grown up. increased.

A note about the use of 'moreover':  I find that many of my students use this often when they first start classes with me.  But in fact, we very rarely use the word in normal everyday British English.  What do we use instead?  We tend to use 'in fact' /'additionally'.
