I went to my driving school for the last two days. (I've been going to my driving school for the past two days.) The coach is always very impatience/ impatient and shouts at the students. Fortunately, I drove a little bit better than some other students. Except for the first class, I was treated relatively gentle by the coach. By the way, it has been tough days for me these days because something has happened. / By the way, these days have been tough for me because something happened.

Note: 

impatience is a noun

impatient is an adjective. 

Adjective desribes/ gives infromation about a noun. What is a noun in the text? The couch. How is the couch? Impatient. I'm impatient. If you said "I'm impatience", that would mean you're not a person. :D

The different between I went to the driving school for the last two days and I've been going to the driving school for the past two days is just when it happened. The first sentence refers to the time/moment which is already over, somewhere in the past. Yesterday was the second day as you had gone there. Whereas the second sentence would rather refer to the moment that is still happening and involves the present as well. You went there and you have just come back, but you'll still be going there. 

Your English is genuinely very good. :)

I hope it help. :3

Good luck, 朋友 :)
