Student or Learner
Can anybody read the following sentences and give comments on it? If you see any grmmartical mistakes or awkward expressions, please help me.
Lazy students should be penalized for being late for class and for not submitting their homework on time. Teachers can take off some points for late assignments or for bad attitude, such as not being attentive in class.
In your question, "grmmartical" should be "grammatical".
In your second sentence, I would change "for bad attitude" to "other problems". Not paying attention in class is not necessarily evidence of a "bad attitude".
