Do it all in layers. If you lack confidence, then use PhRing for some course you are good at.
And also be sure to mind map. Use MMing as much as you can for all your lectures & activation. I taught MM to a boy in high school. He graduated at the most improved student in his class. He told me it was all thanks to MM. He continues to use it in college & is graduating early. He thanks me every time he sees me.
