More exercise with alternative style (Enhancing with the learning-aid stuff)

Practice

recently, ive been learn multivariate integration (university). but i realize that there is no practice section in the subtopic instead there was in the last topic. it is little bit demanding, but it will be great if there is practice section after every subtopics. it will help guide their memory to recap what they have learn just for a while

Worksheet

im also demanding that khanacademy have some worksheet that student can do it online and also can be downloaded it to be printed out as their homework.

Guide

but the  worksheet is not just directly give the question with answer but with the guided short example that was comprehensive, for every stuff that have learned. it is kind of irony because khanacademy do have video, but i mentioned about vpd:

Rationalize

it look like creating memorizer, as the opposite we want productive student more. but on the other hand that was one part of the bloom's taxonomy. maybe it was not much but it will be a great kickstart to those who want to just coop with the current system. this was example suggestion~
