I purchased the course, the index cards and the extra quizzes. I don't have the book nor did I take any classes or go to any programs. My schedule was too busy, so I self studied with Brandon's incredible bundles. I HIGHLY recommend his course and the extra quizzes were chef's kiss.
PS: the combination of the course outline, the cheat sheets AND the videos is the key to really understanding the material. Thanks Brandon!

Very comprehensive and scholarly presented . Kudos Brandon!

The practice test really helped prepare for the certification test!

Hi these cards are of quality and value easy to learn and just amazing thanks

I just registered class about one week ago, and finished two modules. I have to say this 101 class make the process of preparing the CRCST exam much more easier. I mean each module is kind of short but full of necessary information for the exam and follow up with some practice questions with an answer page. I also have flash cards on the way, cannot wait to see it!!! I am planning to take my exam no later than August probably in the middle of August, hope I can pass it on my first attempt. 🙏

I took my test today for my provisional and I PASSSED! I bought the flash card bundle. I can say honestly your flash cards seem like a lot of hard work went into them. I’ll be honest i didn’t really use them as much but i found your practice test very helpful. I would take them every two weeks and it helped me a lot on my test. So thank you very much.

Taking my CIS in July. These are a very good study guide. Thank You.

I felt pretty confident going into my CIS exam, but I wanted some extra reassurance so I decided to purchase the practice exam. Not only did it give me peace of mind, it also showed me where I could use a little extra last minute studying. The questions felt true to the test and were far better than any of the free study options. 10/10 would recommend!

I really loved this practice exam, it helped me a lot in preparing for my CIS exam. I especially appreciated how the practice exams are linked with the HSPA CIS book, providing page numbers to review whenever you choose an incorrect answer. This feature made it easy to revisit and understand the material better.
