I have a question. I have a biology test coming up soon in a couple of days. Im in grade 11 by the way.
The test will be on:
Polar bonds, non-polar , hydrophobic hydrophilic
Small molecules and macromolecules page 8,10
Know how to recognize the different molecules that make living organisms Starch cellulose and glycogen.
Saturated and unsaturated fatty acids.
What is the basic composition of a fat
Recognize an amino acid. The structure of proteins: the polypeptide chain, the alpha helix, the tertiary structure
Which bonds are covalent and which are hydrogen bonds.
What is a nucleotide. Recognize the formula
Testing for macromolecules.
The fluid mosaic model and its evidence.
Through the cell membrane
Passive transport; simple diffusion, facilitated diffusion. Channel proteins and carrier proteins Know how to interpret of rate of diffusion graph. What affects the rate of diffusion
Osmosis. What is it.
Hypertonic, hypotonic, isotonic ( all with respect to the cell) solutions and their effect on animal and plant cells
The sodium/potassium pump.
AND THE LIST GOES ON AND ON.
ANYWAYS DOES ANYONE KNOW WHERE I CAN GET LIKE A FAKE TEST OR A TEST THAT WAS DONE BY ANOTHER SCHOOL OR SOMETHING TO HELP ME TEST MY KNOWLEDGE ON THESE THINGS.

This is what I used to do when I was a student and will face an exam:
Try "fake test" or "challenge" from any textbooks. It usually locates after a chapter to test whether I really understand to the whole chapter or not yet (comprehension).
Or start to "teach" myself by explaining what-why-where-when-how-etc of each definition. This help me out to refresh my knowledge.
Then I will be ready for written or oral examination.
GOOD LUCK! 🙂

Nice opinion on that Dr. Stein, Self study is important.

A reply to 007:
There are excellent texts available on these materials. I have a question for you. Where were you when class was in session? Is it indeed possible that the materials you have indicated were never mentioned in class?
If so, I have a few suggestions: 1. file a lawsuit against your school for testing in subject areas that have not been covered. 2. If these materials have been covered in class, I respectfully suggest you check the latest edition of Morrison and Boyd’s text on organic chemistry or similarly fine texts by Kemp and Vellachio and read and study with a friend.
Do not make the mistake of committing things to memory. It won’t work. I have some easier advice. Learn general ground rules for all sorts of chemistry. Organic chemistry differs little from general chemistry. Do you understand the concept of valence? How is your grasp of basic math?
I am curious about all this as I actually only finished ninth grade before dropping out of school and later getting a GED after leaving the Indian reservation. I skipped a year of college because of CLEP and the fact that I had read a lot of books on my own from natural curiosity. I later earned a doctorate and some other degrees. You have but four years less of formal education than me.
Your text books may be poor. Mine were on the "rez" but there were books at the library and I read. I would ask why you waited until this late to learn that you had no clue as to basic concepts of chemistry. Why? You are close yo becoming an adult. What is your responsibility here?
