I LOVE Khan Academy!! I’m currently a mathematician college student and this website has helped me out soooo much!! I honestly don’t know what I would’ve don’t without all of their helpful resources. They have a plethora of topics to choose from that you can easily access and learn from. I love the informative videos that they provide and the mini tests/quizzes that are also included! And even better.... it’s free!!! It’s so great being able to come onto this website and being able to find all of the topics that I was/am struggling in. Every summer before classes start again, I come on here just to refresh my math skills and just to prepare myself for the new semester. If you haven’t already, I would definitely recommend taking advantage of all the great free resources that this website provides.

I took no ACT or SAT courses and Khan Academy was a godsend. Their videos and explanations are thorough and UH FREE, so you can’t go wrong. They also make videos on literally every subject and topic so whenever you want extra help or reinforcement or to learn something new, Khan Academy knows how to pull through. I cannot recommend this enough, it helped me with my exams and to get into the school of my dreams without spending a single dime.

I’ve personally uses khan academy since I was in about 4th grade and as a sophomore in high school I’ve realized it’s still helpful to this day. I ended up missing a lot of school last year and math was my hardest subject but by the end of the year I had a B on my final and that was from me spending up to an hour on the website doing math problems and learning what some things were. I totally recommend this app!

This is a great way to learn about things you may have missed in school and a great way to refresh your memory on some subjects. They have a lot of college level information too so it can be used as a companion to your textbook or could even replace it in some cases. The videos go through concepts step by step and you can pause and rewind as much as you want so you can be sure you understand 100%.

I use Khan Academy in my classroom with my students who need enrichment or review. It is free to use and easy to log on. I love that I can send home log-in information so parents can use this at home if they’d like their students to practice their math (or other areas). I wish this had and English/Language Arts component for Elementary students.

Khan Academy got me through physics and REALLY helped me in Respiratory School. I WISH this had been available the first time I went to college. They explain everything in terms that are so easy to understand. I use Khan Academy all the time whenever I need a refresher.

One of my favorite tools as a lifetime learner, a teacher, and as a parent. The lessons and explanations are very well detailed to purposely learn the content. Exercises are interesting and having used for about 3 years now, it is something that is always improving.
