The app itself is absolutely brilliant and it would've received 5 stars if it weren't for ONE thing... I'm hard of hearing so with the videos, I have to ramp the sound right up AND have the transcript on at the same time, I honestly don't mind that. I DO mind that when every question is answered correctly, my ears are then assaulted with this brash bell noise EVERY single time! Even with the sound low, it's discordant tones makes me uncomfortable and I end up closing the app in frustration. Every. Single. Time. There are no options in settings for sound control and that is why KA has 4 stars (sorry, I really did want to give it 5, it's ridiculously good otherwise!)

There's a performance issue whenever opening the app. I cannot click on anything until about 2 minutes has passed, when all clicks happen at once. Another problem is that it doesn't hold my progress when closing the app. I hoped to use this to revise on the train but I have to switch app to show my train ticket, then my progress is gone and the 2 minutes delay is back!

I love this app sooo much. It has the greatest feature in helping you prepare and equip yourself with anything you want. I can't count how many times it has helped with tests and exams and sometimes when I don't understand my teachers I come here. From the notes, to the videos and the questions set up for you with mastery points. I would greatly recommend this to anyone, you don't have to pay for anything which is quite amazing on its own. Khan academy is the real deal!!!!!!!
