Hi guys,
m name is Maira and I am the tutor for Chemistry and Introductory Chemistry for the year 2019.
Since most of you have very similar doubts and questions, I decided to make a document with some
FAQ and advice. In case you still have some questions and/or you are having trouble with some
exercises, let me know. However, I feel the need to tell you that I do not always know how to solve
all the problems. Also, please, do not contact me the night before the exam, because I will not know
how to help you then 
Good luck with your exam!

Solve as many exercises as you can!
Do not hesitate to ask prof. Marini for office hourse if you have doubts, he is very helpful
and likes when students show effort.
The exam consists of a few structures to draw (for example lactose, phenol, etc.) and some
problems to solve: most of these problems are either cells or equilibria. However, everything
can be included in these types of exercises, for example pH, salts, buffers, etc.
For the carbohydrates: know both the Fischer and the ring conformation.
Try the written exam even if you are not completely ready, at least you will see how it is .
Do not get discouraged if you do not pass it: I passed the written one on the second try and
oral on the third .
YouTube is a great professor.
