I recently found a website that is a perfect source to find geometry formulas. It was very useful when I forgot a page of notes with many formulas I needed. This website is very straight forward and has great visuals that helped me understand the math concept. It is very reliable seeing as my answers matched up with the ones on the key, and for that reason I would definitely recommend it. All of the formulas are on the same page, making it very helpful and efficient to do my review worksheets.

This site was especially helpful for me to research information that I needed for a presentation I was doing in Global Studies. I found that Fact Monster was a very reliable source, with a lot information. The information was as useful as facts about countries, to formulas and strategies for math. It is a very simple, helpful site that is easy to navigate.

This website offers hundred of SAT and ACT practice questions for free. It is very useful to get adjusted to the types of questions and trickery that standardized tests often do. This also gives you basic formulas and vocabulary to study!

Lecture 1 emphasized on light as a particle, matter as a wave and the Schrödinger equation. Light as a particle was described through various examples of photon ejection. Matter as a wave emphasized on Louis de Broglie's formula while Schrödinger's equation emphasized on, well… Schrödinger's equation (and its partial solving)!
