These are free and you might find them useful. If you go to the langmedia website check out the "Formal Spoken Arabic Dialogue collection". This helped me with listening. The madinah books are great, to me they are the best resource for arabic. There are videos of classes for free as well as the book available for download on lqtoronto.com. They are great for MSA or Classical I think, if you can get through them you need only to work on your vocabulary and listening to be at a high level in Arabic.

I just love this online dictionary which is very useful if you are reading an Arabic text and do not know exactly what the name, the verb, the preposition means ....Arabic to English aratools.com

Medina books are great but for really Classical Arabic.

On 3arabya.org you will find the book "teach yourself Arabic" from Smart and Affolter it teaches a more contemporary Arabic.

Look at the at the Medina books they are freee and excellent for grammar. You even find some drills on YouTube .Their author lives now in Canada and has plenty of material.

there is also a Palestinian girl on YouTube who speaks easily four languages, she has her own channel " learn Arabic with Maha".

for books and grammars you find many PDFs to download for free on 3arabya.org

Enjoy!
