Stuck? Stop searching through 300-page textbooks. ArbAI explains complex topics in plain English, instantly.
ArbAI response:
Why is Xylem correct?
Xylem is responsible for transporting water and dissolved minerals from roots to leaves. It consists of vessels and tracheids. Phloem, on the other hand, moves sugars and nutrients.

Don't take our word for it. Here's what they have to say about ISA Certified Arborist Flashcards.
Congrats! I fully believe that the ISA flashcard app was the reason that I passed. I failed my first go of it, but after spending the money subscribing and basically glooing myself to the app, I passed the 2nd
BBrianFacebookWhat a great way to study, a lot or a little at once. The best feature of this app is the AI attached for wrong answers. Wow! If you are unsure about the test, this is where it’s at, everything you doubt yourself on, the app has got all the resources cited and answers with the whys. A must have.
GGregApp Store Reviewtaking my test soon and this app is very helpful
RRickyGoogle Play Review
Had to learn along the way, and didn't have a formal background, but it's possible to do it! I highly recommend this ISA Flashcards and the 4th edition study guide - was able to pass on the first try after around two months of studying intentionally.
NNatalieFacebook
Get the ISA flashcard app. If you are serious about getting the cert, that app helps tremendously. It is 1000% worth the subscription and you can cancel it after you
NNakeFacebookWorked like a charm, it’s been a while since I had to use flashcards but it worked perfectly! The repeated questions if you got something wrong really drills the correct answers in your system
YYungyulaApp Store Review
I failed the ISA exam three times. This app with the AI is going to be what gets me the gold. I have coworkers that have used this and passed and I’m recommending to others now.
NNathanApp Store ReviewBeen studying for 2 weeks. This is the BEST combo with the text book, and ARB AI is much better than a generic AI
UUserApp Store Review
Great study tool for ISA exam. The exam questions are obviously different from the actual exam, but my average for the actual exam and the practice exams on this app were the exact same.
DDeanGoogle Play ReviewThis app has really helped me to study longer and devise a study plan. Reading textbooks alone is mentally exhausting but having different quizzes and exams keeps me going. I’m much more confident going into my exam this time around.
WWakakakithdoeApple ReviewHave an exam coming up so I needed a way to review. App was amazing and fast. The AI helped too
