Khan Academy: PreCalculus App Reviews

Indeed

Some of the Exact same videos as calculus 1 app; only with different names. This is precalculus, not calculus, therefore, videos should be more beginner-friendly and more introductive. Update and change the first few videos please. Thanks much.

this take forever to load!!!!!

Highly recommend!

These programs are awesome!

Love the interface! Your time, knowledge, and willingness to share them are much appreciated! Quick and small correction for the first problem in video number 5, limits with brain malfunction, I believe you added the factors in the denominator instead of multiplying them as indicated by the previous step.

Pretty good, did learn a few things. Thanks

I am going to recommend to my teacher that she recommends it to her students since most of us have iPods or iPhones. Its perfect if school just isnt enough.

I love this app. I learned a hella lot, so gunna be ready for pre cal next year. I totally recommend this app.

It takes a while to load but I love it I use it on this program on the computer and now on my iPod I love it

Its a great way to learn or just refresh what you already learned.

If this app didnt have an existence, I would be failing miserably!

It works perfectly! And has really helped with school!

Not too shabby. Pretty helpful

I love this app, its the only thing keeping me from lost confusion :D

Ive always enjoyed the apps but they arent working for me on iOS7. Please get support for the new software.

I downloaded this the other day but I cant get anything to work. Not sure what should be happening when I highlight a topic, but nothing happens. It just turns the topic line a different color .

The problem is fixed. I needed these refreshments on-the-go. Thanks!

Chapter 5, 1st problem, there should be 6/(8*4) but you did 6/(8+4). Fix it!! Thanks

The speaker wastes so much time with fluff talk. Its just not enjoyable or an efficient use of my time.
