I learned a lot in this class. Professor Sievers drops your worst test grade and gives you extra credit for completing your work book. Final is optional, those with an A have no reason to take it, for others it can only improve your grade.. In this class you will learn about black holes, time travel, the density a star/sun must be to go supernova

Mr.Sievers is the most interesting and exceptional teaching I have ever known!He is extremely organized and never falls behind.

The tests are not hard if you study....DUH!

He's a really good teacher. Most students don't understand him because he's very knowledgable about astronomy and can talk in a way that may be hard to comprehend if you're not very good at science. You get a lecture guide which really helps and can be used for extra credit. Only 5 tests, but they make up your whole grade.

No homework. 15 extra credit points are possible if you turn in lecture guide. Don't buy textbook only lecture guide is needed.

Very nice professor, lectures can get kinda boring at times but okay overall. He gives you a sheet in the beginning of the year that spells out what's going to be on the test, but it's still very hard material. However, you can drop your lowest test grade, and there's also easy extra credit. The scale is very forgiving as well (A 88%+, etc).
