In addition to libraries, tutors, and on-campus resources, many of today's students rely on web-based study guides. Below we consider comprehensive, user-friendly guides for biology, history, literature, and other major fields of study, as well as some generalized sites whose study tools cover a range of disciplines.
But before we begin, please note: online study guides should only be used to supplement course texts ― not replace them. In order to truly succeed, college students simply must complete any work they are assigned. Also note that copying materials from study guides is considered plagiarism, an offense punishable by suspension or expulsion from most places of higher-learning.
At the college level, organizing course notes can be a time-consuming task in its own right. We've identified three sites whose software allows users to easily record and manage notes.
- Evernote: Originally launched in 2008, Evernote creates searchable, fully transcribed notes by capturing text, images, audio, and video files. Users can also bookmark certain sections, and then easily access them later. Key features include:
- The Evernote app, available for most major smartphones, desktops, and tablet devices.
- Skitch, another app that lets users add signs, drawings, and other symbols to digital presentations, photos, and other media files.
- Penultimate, an application that allows tablet users to write and draw on their touchscreen using a special pen-like device.
- UberNote: This tool stores all course materials in a cloud-based location, making individual accounts accessible from any computer or web-supporting device. The user-friendly interface enables multi-page viewing, dragging/dropping, and other helpful functions.
- Zoho Notebook: This free online service is available to anyone who creates an account. The site is geared toward teachers and professors, allowing them to create live pages (known as ‘Books') and upload content to students who have been invited to the Book. Zoho Notebook is also useful for creating small study groups.
- Book creators can add video and audio clips, images, live website widgets, and other media files.
- Book owners will be able to view (and, if permitted, edit) the Books created by everyone on their contact list.
- Books are compatible with Skype and and Google Notebook, allowing for easy syncing between programs.
