My site is www.understandbiology.com and i request any one of the expert here to review my site and tell me whether its good for adsense or not. thanks in advance!
Any niche can be good for Adsense, your niche does fit with adsense very well. 1. It is an education niche, if it was just about Biology this might be different, but since it is about learning biology, you should be able to get a high CPC for a lot of the keywords. 2. Have adsense content on the first page and preferably on the sidebar or in the side of the content. Good Luck
