How can I study or prepare myself for an exam with the help of my Android device? I want to learn a language or prepare for an exam with the help of my Android phone or tablet. 

Are there any efficient and fun methods out there to do so?
I could list up a bunch of stuff here now, but that would get quite long. So let's better organize it by groups:

Covering multiple topics

First, of course, there are mentioned Flashcard apps (best-rated here are probably Learn Easy and AnyMemo -- a longer List can be found at my AndroidPIT overview Vokabeln &amp; FlashCards (Google Translate version here).

These are not only restricted to languages, as mentioned AnyMemo shows1: being able to also use images, you can use it for everything -- think e.g. of images of molecules, electronic wiring examples, and others.

 

Languages

Second, there are the "big language guides" -- again I can refer to an overview at AndroidPIT: Sprachführer (and the Google Translate variant here). Though this latter mainly addresses German native speakers, the end of the list has some generic hints.

 

While FlashCards &amp; Co focus on learning words, the more complex language guides also cover grammar and complete phrases. I guess best is to use a combination. As for the FlashCards, any solution should do: they are mostly not language specific. Other with the language guides, where it lies in the nature of this type that it has to be specific at least to the target language you want to learn. Examples here include French Class Demo3 and Italian in a Month Free4.

A third category should not be forgotten to mention here: Get yourself a good eBook Reader, and add some books to it which are written in the language you want to learn. I recommend Moon+ Reader5 here, which already includes a huge Online Library list for multiple languages (which actually is sorted by languages even), so the reader immediately has some ressources at hand. Having trouble with some words while reading? Simply long-tap the word to open a dictionary -- either online translation, or an offline dictionary like Fora or ColorDict6, which both can deal with StarDict files saved on the sd card. Being able to mark and even annotate with Moon+ Reader (see the picture5), one could also use this app for other subjects/classes.

 

Number four now should be obvious: There's that Youtube app one could check some language specific movie[clip]s with. Or get some other movie player (MoboPlayer probably being a good choice), plus some videos in the targeted language.

Guess number 5? Right: Music. There are plenty of music players around, and songs to pick. Repeating them over and over is baking some phrases to ones brains :) Beside this fact, there are also some audio books and language-learning audio files around.

Science

So far on language-learning -- but your question was not restricted to that, as I just notice. So let's go for some more possibilities -- pointed out in the AP overview Formelsammlungen &amp; Referenzen (Google Translate: formulas &amp; references). There are tons of references for chemistry, like e.g. the very famous Merck PTE HD (periodic table)7, mathematics calculation helpers and references like e.g. Mathematics8, physics references, electronics, stuff for engineers... So learning is clearly not restricted to languages.

 

School Organizers

Learning for school or study? Multiple subjects to cover, and courses to keep track of? This also can be covered using your Android smartphone or tablet. The AP overview dealing with this would be Stundenpläne und Schul-Organizer (Google Translate: school organizers). From simple timetables like School Schedule9 to just keep track of what subject is running when and where, to apps also keeping track of related tasks and even silence the device during classes (e.g. My Class Schedule -- note the tiny numbered boxes on the blue items in the screenshot10, which indicate connected tasks), you can find many solutions.

 

Summary

To sum up: There's a lot of stuff you can pre-load to your tablet -- and then use to learn on-the-go.
