...and still get decent grades?

I'm asking because I was enrolled in an intro chem class this summer. However I missed 3 classes (including 2 labs) due to a cold. That's too many days to miss during a 6-week summer semester, so I dropped the class, rather than take zeros for things that I wouldn't get to make up.

I tried to sign up again for intro chemistry for this Fall. Yet there was only one section on the schedule for that class, and it was filled. Don't know why they only had one section for a lab science class, when it's such a big requirement.

Anyway, I'm just wondering if anyone else skipped over intro chem and still did just fine. Besides, some academic advisors told me that I might not necessarily need the intro class.

By the way, I'm pretty good with science...generally an A student with science and other subjects. Every once in a while, I get a B. That's just to give an idea of my academic abilities.

Back in 2003, 3rd infantry and 101st Airborne Div. soldiers kept finding oddly shaped barrels of chemicals that field-tested out to be sarin, tabun, and other blister and nerve agents. The government later said that it was all simply very concentrated pesticides.

Now, back in the 60's when I was a hippie writing nasty letters to our congressmen trying to get DDT and other pesticides banned, we used the argument that they were just watered down chemical weapons.

So, just how concentrated do pesticides have to be before they can kill a human being? Can they possibly be used as chemical weapons? And while we're on the subject, if Timothy McVeigh killed all those people with gas and fertilizer, and the 9/11 terrorists basically used jet fuel, what exactly is the kill ratio required to get that WMD label?

I have a specimen that I believe to by either polypropylene or some type of paper/cardboard. I was planning on using hydrogen peroxide to test which it might be. Any ideas on whether or not this will work? The sample is only about the size of the head of a pin.

Synthesis problem for organic chemistry

to get racemic 2,3-dibromobutane from propyne you have to take propyne through 4 steps. I have figured out that Br2 is one of the steps, but what are the other 3 steps to complete this reaction?
