Test coming up in mid August

Hey guys, I'm new here and I need a little advice! Let me start off with a little background info.

Age: 20 (21 in a month)
Height: 5 ft 8
Weight: 120lbs
Metabolism: Ridiculously high
Exercise: Minimal. I do longboard a lot though.
Smoking history: After quitting for a bit I picked up smoking again. About an 8th a week of some decent green. Did that for about 4 months.

Okay, so I have to take a drug/alcohol awareness class sometime in the not-too-distant future. The nice thing about it is that I can schedule it whenever I want, so there hasn't been any huge rush. The not-so-nice side is that the class requires you to take a drug test at some point throughout the 3 week session.

I'm returning to school in August and decided I wanted to get the class over with before then, so I have been working on quitting the green. My original plan was to take the test on July 11th (today). I tried to clean myself up and I quit smoking for 17 days. Yesterday I went to walmart and bought a take home drug test and hoped for the best. I failed :(

So I looked when the next set of classes begins and found out that the next opportunity to take the class is August 15th (34 days from now). For whatever reason I decided to toke a quick bowl with a friend or two last night, knowing that the test would be in a little over 30 days. Now I'm starting to wonder if that was a dumb idea hahaha (of course it was lol)

Anyway! I figure that I was 17-18 days clean, then toked a bowl, and now I have 34 more days to sober up for this dumb class.

Do you guys think that is enough time to sober up naturally without the need for dilution? I want to walk in and take this test no strings attached. As you can see from my stats at the top of this post I'm definitely not a very big guy lol (I'm really small, with a ridiculously high metabolism) I'm giving myself a grand total of around 50 days (with a dumb decision made on day 18) without smoking.

What do you guys think? Will the next 34 days be enough to clean up a small guy like me?

Theres no telling because each persons body is different and there are too many variables to take into consideration. Only a home THC test kit (using the first urination of the day) can give you that answer.
