text: In classes that require previous knowledge from lower levels for example math I remember when I went from algebra 1 to algebra 2 it was extremely hard for me to understand algebra 2 because I couldn't use what remembered from the previous level since I had forgotten it over the summer. In this case if I was given a worksheet or some packet that I could have done over the summer to help me remember and use algebra 1 for algebra 2 it would much easier for me to understand what i was being taught. From personal experience I know I wasn't the only other student who struggled from a similar situation like this, reasons like this is why most teachers give out there own assignments for students to do to help them remember old previous concepts and methods from previous years to understand their class.
