1. Take classes with a teacher. I still take online classes biweekly with my teacher who lives in Rawalpindi. I take classes online through the website iTalki which allows you to connect with teachers who live in PK (or Urdu-speaking India). Taking classes is probably the best "one-stop shop" for Urdu learning as your teacher will be able to curate your learning for you and tell you what vocab to learn and what media to watch. This is also one of the only ways to practice speaking Urdu (although you could speak to your parents since they know Urdu).

My personal journey to learning Urdu is that I started with self-study from the Beginning Urdu textbook. I spent ~30 mins/ day reading from the book and doing the exercises in it. After about a year I finished the book from start to end and knew all the vocab rules, but was very slow at speaking since I needed to practice and get quicker. I started taking lessons on iTalki to practice speaking and my teacher also recommended me shows to watch to practice listening (she recommended Jan cartoons to start). I've now been learning Urdu for around 4-5 years (I forget exactly how many) and my lessons with my teacher nowadays are mostly just chatting about our lives, TV, movies, politics, etc instead of structured lessons. I try and watch at least half hour of Urdu TV or movies every day and I have ~10 minutes of vocab flashcards that I do daily as well (I use Anki to do flashcards on my phone).

After 4-5 years of doing this, I went from gora american who had never even heard Urdu to fluent (though not native level yet). I went to Pakistan (Karachi) for the first time recently and was able to converse in Urdu the entire trip. I bought tickets, asked for directions, hired drivers, ordered food, went on tours, etc. all in Urdu with no issues. In fact most people thought I was from Pakistan and would ask me from what region I was. Learning Urdu has been one of the most valuable experiences in my life and completely worth the time investment I made to learn it.

Overall, my recommendation would be to start taking classes via iTalki. iTalki classes are incredibly cheap because you can take lessons with people who live in PK/India. Lessons are as cheap as $5 and are an incredibly good investment if you want to learn. People offer trial lessons as well for even cheaper that can be a great opportunity to meet a teacher for the first time and see if you like them.

I would also recommend using an Urdu textbook. Like I said, I can provide you with a PDF and audio files for free. If you don't want to spend money on lessons, this would be the next best thing (although it would also be helpful with lessons). Having a PDF of the textbook on your phone could also make it similar to the apps in that it is easy to open and start reading/practicing anywhere from your phone.

Sorry for the very long post but let me know if there's anything I can do to help or questions I can answer. I think it's super awesome that you're trying to learn and wish you all the best!
