Easy if you clear all of your concepts, mark my words, book has all fruitful notes, dont skip anything. Every thing is important, focus on every topic, and at last revision, mainly concentrate on the topic which are repeatedly asked in papers :)
All the best. :)

In the file biological molecules,in part e, there are mistakes,
The fatty acid chains have no electrical charge and so are not attracted to the dipoles of
water molecules. They are hydrophobic.
The phosphate group has an electrical charge and is attracted to water molecules. It is
hydrophobic. [HYDROPHILIC]
In water, a group of phospholipid molecules therefore arranges itself into a bilayer, with the
hydrophobic[HYDROPHILIC] heads facing outwards into the water and the hydrophobic tails facing inwards,
therefore avoiding contact with water
ANYWAY THANKS ALOT FOR THE HELPFUL NOTES(y):):)
