The lesson states:

To express to need + [noun], you will use :avoir besoin de/d' + (article) + noun

The examples cited show the use of the indefinite article but none include the definite article and it could be implied that the definite article is never used after  avoir besoin de/d' which is obviously wrong. It is the old problem of the specific vs the general. Since this is a perrenial problem for French learners, it might be an idea to spell it out more explictly in the lesson.

For the french imperative he conjugation is same as the present tense except that for -er verbs, the last -s is dropped in the tu form. ... 

In the phrase "mais j'ai trouvé très utile d'y ajouter les exercises Hanon que tu m'avais recommandés"
shoudn't it be "exercices" instead of "exercises"?

I understand that this is an idiomatic phrases that means "I know something about ..."  Just curious.  How do the reflexive "me" and the preposition "y" refer to or mean?  "I am familiar with myself" and "at ... in that area"?  The "y" seems redundant since you say "en moteurs" at the end.  Why not, "je me connais en moteurs."
