<p>Can someone explain to me Hybrid orbital bonding, sigma and pi bonds?</p>

<p>Also, how hard is the real test compared to the sparknotes test?
Here are my scores after studying most of the info:
Barrons:I took 3(740,770,800). In the 800 i missed 7.
Princeton: 770, 800, 780. My tutor said the 3rd test was hard
McGraw hill: 770, 770, 800(missed 3)
1995 test collegeboard: Wow i messed up on this one. Took it consequetively after another test I got 770 missed 7
Sparknotes: I just took one I got 760, and this is after studying.
I took Kaplan before I started studying so I did pretty bad.
I haven't taken the 2006 blue book test yet, im saving it. I looked at the chart on the back and it says I can only miss 3.</p>

<p>Orbital hybridization is tricky, but it will definitely be covered in detail by any textbook that explains chemical bonding with reference to quantum mechanics. I suggest you get your hands on one of those, because it’s really not that easy to explain.</p>

<p>btw i missed 9 on the sparknotes</p>

<p>anyone can help me with the score questions?</p>
