Flashcards and Memorizing in Languages
Some people have good memories or can just memorize new words as they come, some need to be constantly reminded, but whatever your situation, there are ways to help yourself with memorizing things in languages.
Vocabulary lists and lists of grammar rules or phrases can be fine, but they aren't always effective.
One good way of memorizing is through using the concept or word over and over, AKA practice. This can be done in many ways, like writing the word repetitively or saying it out-loud often enough or reading it over and over.
There are also flashcards (either physical or online, personally, if I were to use them I'd choose online, especially if there's a nice app). Some good sites include: https://ankiweb.net/ , http://www.studyblue.com/ (don't worry about joining random "classes", it doesn't matter) , http://quizlet.com/ . Quizlet & StudyBlue have nice apps, but Anki only has apps for jailbroken iPhones in Cydia or on Androids (maybe Windows phones too, I'm unsure).
There is also the association method. The best place I know of to learn this way is Memrise, where you learn vocabulary and whatnot via pictures or stories or jokes or any sort of relation you can. For example, I once saw someone showing this off and using the Spanish word "caber" meaning "to fit" as an example, and the association was a meme-like picture saying "it's hard to fit a bear in a car". Get it? "car-bear" is pretty much how you pronounce "caber" (with an extra "r" though). This relation method can work very well, here's the link http://www.memrise.com/ (also, if go to YouTube and search "cat academy" to find an entertaining intro to their new iPhone app).
Finally, there is a method that requires no fancy technology or anything, but just a fairly basic phone. Because phones have reminder functions of some sort installed, you can set periodic reminders to help you put a word (or concept or phrase) into long term memory. This is especially useful if you space the reminders well and if you don't immediately see the word/phrase/concept, but rather have to try to recall, then you scroll down (or something to that effect) and see the reminder both isolated and in some context (and maybe broken down into parts too).
