Here I am, on this grey Saturday, busy with your compositions. I'd like to share my thoughts with you... What am I feeling? What am I worried about? Let me put this briefly: I am thinking it would be a good idea if we came back to "the very beginning" and started looking at basic tips to improve our writing. Mmmm... Let's see.
A wonderful website to start with would be this one; but specifically, I'd recommend you to go straight to the Editing section, which is really helpful to revise (or to learn) essential basics on the Writing Skill.
So, my dear students... I think my weekend experience with your compositions might change our schedule for next week. We'll talk on Monday about it.
