A【四川省广元市2017届高三第二次高考适应性统考】

When you’re having a hard time with your homework or when you’re preparing for your term paper, these student-focused websites can help you with just about anything you need. The key to getting the most out of these online resources is to know how they can best be used to your advantage.

    Facebook

    Although Facebook can be one of your biggest time-wasters and distractions when you are supposed to be getting work done, it can also be one of your most valuable resources. Most of your classmates will probably have a Facebook account, so anyone you need to connect with about a class you missed or about a problem is usually just a few clicks away.

    SparkNotes

    With a free library of history timeline, philosophy study guides and library summaries, SparkNotes has covered just about any reading-related jam you find yourself in. Just run a search for the book, play, or short summary of the material you are supposed to read.

    Amazon.com

    Do you finish every term with many expensive textbooks you will never open again? Instead of letting the money spent go to waste, get back some of your cash by selling your books on Amazon.

   RateMyProfessors.com

   Choosing new classes can sometimes be like trying to pick out your clothes in the dark, a total guessing game. Which teacher gives out the hardest problem sets? How much homework will that history professor give you every week? At RateMyProfessors.com, students all over the country rate their professors on quality, helpfulness, and how hard their classes are.

   Wikipedia

   While Wikipedia isn’t aimed specifically at students, it is difficult to think of another website that does more to reduce the pain of paper writing and researching. Wikipedia gives you a quick way to find sources and get the details of almost any topic you need to research — all without walking to the library.
