One of the common challenges for many Algebra students is not having a solid understanding of Pre-Algebra. So many students complain that they forgot or never fully learned fractions, decimals, percentages, ratios and word problems. Even memorization of multiplication & division tables can fade over time. These concepts are critical for middle and high school math. A better understanding can not only boost confidence but can improve grades and SAT scores. Spend time with a tutor or using different websites to review topics from previous years. It will help, exponentially!
