Visualizing Colligative Properties

Posted by Hunter Archibald on 7/1/15 10:00 AM

To simplify colligative properties, picture what is happening when you dissolve a salt in water. We know that increasing the concentration of ions has an effect on the boiling and freezing points of water. How do you remember which way?

The Basics of Retrosynthesis

Posted by Cynthia Liu on 5/16/15 10:44 AM

No…not that kind of retro.

People often dismiss organic chemistry as “all memorization”. I disagree – organic chemistry is just a series puzzles based on a few basic concepts (electronics, sterics, orbitals) that come together to answer almost any problem you might encounter on your homework or tests.

Study Skills: The Bionic Power of Mnemonic Devices

Posted by Richard Gold on 2/6/15 11:00 AM

woody allenRobots are awesome, but don't become robotic while using mnemonics!

Mnemonics: from the Greek “Mnemonikos:” of or relating to Memory.A device such as a verse or formula or rhyme used as an aid in remembering concepts. Named for Mnemosyne, the goddess of memory in Greek mythology.

The most popular kind of mnemonic device is known as “expressions/words.” This refers to the method whereby the first letters of the items to be remembered are organized into a snazzy and memorable word, phrase, or sentence . Almost all algebra students know “Please Excuse My Dear Aunt Sally,” but just because you’ve graduated high school doesn’t mean mnemonics stop being useful—in fact, they’re more important than ever for developing good study skills. In an effort to remember the 11 organelles in the cytoplasm of eukaryotic cells, even a professional biologist will rely on a sentence like “Nobody Can Roast Really Great Steaks Like My Neighbor’s Cousin Vinny.” For our MCAT tutoring students in Boston and New York, mnemonics are the very breath of life. But it’s important to understand that there are way more ways to design mnemonics than just simple sentences. Today, I’d like to show you some.

Sing It!

If you are clever or musical enough you can create a song or jingle like the famous “ABC” song sung by generations of children. Sometimes these musical interludes can be only one memorable line. Just apply your own words to a song you already know! A current advertising favorite seems to be 1-877-Kars for Kids, or if that is too lame—and Cambridge Coaching apologizes for having put that godawful tune in your head—then how about “Every kiss begins with K?”

Biology and Chemistry Tutor: Of Acidity, pH and pKa

Posted by Entela Nako on 4/2/14 8:54 AM

 
 
When it comes to the advanced science classes you will take in college, there is usually a clear distinction between the kinds of material covered in each of them. For example, the material you cover in biology classes is quite different than that covered in chemistry classes. However, there are some topics that know no boundaries.  Today, our biology and chemistry tutor explains how the concept of acidity applies to both disciplines.
