Passive vs Active Reading
Have you ever found yourself investing a great deal of time into reading your notes, only to realize that you don’t remember a word of what you just read? Do you find yourself investing a great deal of study time, but it doesn’t appear to help? You may be attempting to study passively, and your […]
Organic Chemistry Summer Survival Tips
So you’re taking organic chemistry over the summer? Perhaps this decision is your personal choice, or perhaps academic or life events dictate that it has to be this way. On the upside you will be getting a 12-14 week course out of the way in a span of 5-8 weeks. On the downside, you will […]
How Reading Your Organic Chemistry Textbook Prior To Lecture Can Save You Hours Of Study Time
Proper study habits take time to develop as a college student. Even the most conscientious students may not be aware of all that is required to properly succeed. As for reading your organic chemistry textbook? eh, that’s something you do the night before exams, right? WRONG! Think about it what they told you during […]
Turn Off Your Cell Phone
Do you sneak glances at your phone while trying to be productive? I’m guilty of it, too. It just takes 2 seconds to see who sent that text, another 5 seconds to reply – no big deal, right? WRONG! If your ideal 45-90 minute study session is constantly interrupted, how much work are you really […]
