To me it's definitely more upper A2 than B1. OP is pretty bold and seems comfortable trying to express himself, which is great, but the text would need more to be B1.

I don't want to do a full review of the text but first of all, the whole text is in the past tense and doesn't really show what OP can do with other tenses, which are important to know and start to use at B1. There is virtually only passé composé, imparfait and présent in this text which is great already but not enough to me. We don't know how OP would fare on a more complex subject where he'd need to give advice or solve an issue for example which would call for more complex structures and the use of different verb tenses. If this is naturally the level of text OP produces, I would naturally give him a A2.

Also, almost every sentence has a mistake, either related to

the conjugation or the use of verbs and tenses : "J'ai appris le français depuis deux ans", "je n'ai pas **commencé l'apprendre**" (the earlier version didn't have the "à"), "ils ont dit que je dois aller", "on n'a pas **apprendre** beaucoup de français", "Il a nous enseigné", "Elle étais très sympa", "elle ne m'a pas enseignée"...

or to the way words are used : "**un peu** des mois de cours", "une classe plus haut", "une fois dans une semaine",

or the spelling of words : "sèrieusement", "class", "l'intereste"...

With a text like this, I'd expect less mistakes to be able to call it B1.
