Balancing redox reactions is an essential skill for the Chemical and Physical Foundations section of the MCAT, the GRE Chemistry Subject Test, and the AP Chemistry Exam. Today, we will learn how to use the half-cell method for balancing redox reactions in acidic and basic solutions. We will first balance a redox reaction in acidic solution, then we will balance the same redox reaction in basic solution.Read More

So spring is definitely here, and we’re well into the time of year when you’ll be hearing plenty about the Advanced Placement (AP) and SAT Subject (SAT II) exams.
You might be thinking that there’s very little difference between the two and that both test your knowledge of a specific subject or skill – and to an extent you’d be right. But there are subtle differences in timing, in testing method, and in how you share these scores that our team of experienced standardized test tutors and academic tutors in New York City, in Boston, and online are ready to share with you all year round.
In the spring, discussion of SAT subject tests and Advanced Placement exams is everywhere due to the masses of high school sophomores and juniors taking these tests. It’s common knowledge that these tests matter for college, but it’s not always clear how (and if) they impact the college admissions process, and what the differences really are.
