A short video introduces the things other than carbon that can branch off the main chain of a hydrocarbon. The examples have double bonds, so the practice involves many of the nomenclature rules that the video series has...

Beginning with problems 1-7, Sal works on the next section of the practice SAT from The Official SAT Study Guide (page 611). The problems include simple algebraic equations, square roots, word problems, and graphing.

Sal is having a blast in this video, and his fun-loving attitude will rub off on even your most stressed-out test-takers. Problems 7-10 in the practice SAT require skills in linear equations, as well as approximation and basic algebra.

After giving a situation with a number of reactants, Sal is able to review the behavior of those ions according to their stability. Amines and acyl chloride are used first. Next, he looks at the mechanism at each point to move from a...

Using pie graphs and multiple variables, Sal carefully (yet efficiently) moves through problems 5-8 of this practice SAT session (page 839 from The Official SAT Study Guide). Both beginning and advanced mathematicians will appreciate...

After finishing problem 10 about congruent angles inside a polygon, Sal goes on to solve additional problems involving reciprocals, odd integers, and slopes. Those who have a difficult time moving efficiently through different skill sets...

On the home stretch of this practice session, Sal completes problems 18 and 19 on page 738 of The Official SAT Study Guide. He begins problem 20, but chooses to finish it in the next video instead of rushing the answer. As always, Sal's...

Another SAT practice test from The Official SAT Study Guide is the focus of this video, which starts out with simple problems involving integers, factoring, perimeters, and percentages. Students will appreciate the relative ease with...

Sal deftly solves the straightforward algebraic equation in problem 9 in under fifty seconds. Additional problems involve points on a plane, algebraic word problems, geometric angles, and fractions, some of which he takes more time to...

Help your students get the edge on the SAT with this practice video, which details ways to solve various algebra and geometry problems. Sal finishes problem 18 in this video, changing his pace for understanding, and continues to solve...

Sal clarifies that doing a math problem the correct way isn't really the correct way to do it on the SAT. If students find this statement confusing, they will understand Sal's point after watching him work quickly and efficiently through...

Problems 7-9 involve exponents, inequalities, and geometric figures (diameter and radius), all of which Sal explores eagerly. After misreading one problem, he takes care to correct his mistake, showing students how important it is to...

With pen in hand and diagrams at the ready, Sal demonstrates problem-solving and test-taking skills in this informative video. Problems 7-9 involve inequalities, linear equations, and measuring angles in a right triangle.

Sal demonstrates the methods needed to solve problems 8-10 in this video. He begins his lecture with a more thorough explanation of problem 7 (which he feels he "rushed" in the last video). These problems involve skills such as...

Sal takes viewers into the home stretch of this practice test session from The Official SAT Study Guide. Problems 17-18 are algebraic equations, while problem 19 focuses on area in a given figure (with the use of pi).

Starting a new set of SAT practice problems from The Official SAT Study Guide (page 518), Sal takes students through some straightforward questions involving basic algebra and functions. However, as every math teacher and student knows,...

After leading viewers through the basics of carboxylic structure, Sal uses this lecture to describe many molecules, or classes of molecules, that can be derived from acetic acid.

Complicated word problems and expressions are no match for Sal, and after watching this series, they will be no match for your students either! Sal deftly handles problems involving algebraic equations, averages, and circumference.

Sal notes the important of reading a question very carefully in this video, as he nearly misreads a problem but catches his error before it's too late. Most problems shown here involve algebra skills.

Using the process of elimination, Sal takes students through helpful ways to solve multiple choice questions on the SAT quickly and correctly. Problems 5-6 involve probability and proportions.

Using The Official SAT Study Guide, Sal begins another review session of eighteen problems, six of which are addressed in this video. The problems involve variables in linear equations, angles and parallel lines, and ratios. One problem...

Sal's lecture starts where his last one ended - on problem 13 from The Official SAT Study Guide. Starting the problem over to ease understanding, he explains how to find the pattern in a complicated sequence. The following problem...

Both algebra and geometry problems are featured in this SAT practice video. Students who have a hard time transitioning between skills on tests (average mean, then diameters and pi, then positive integers) would benefit from Sal's deft...

Clarifying that speed matters more than rigor on the SAT, Sal takes care to show students the most efficient and easiest ways to solve various math problems. Those who get stuck on certain types of problems would benefit from his...
