Extremely Helpful
Everything is on point. Perfect manner of teaching.
I am a person that struggles with the typical way of studying. I lack the attention span to actually sit down & read the book, the book ends up reading me! lol The Sterile Guy’s short videos & quizzes give me information in small doses that I am able to retain better because he keeps my attention.
I was lost before purchasing this guide, I wasn’t sure if the questions I was seeing online were legit or not but after going thru the modules and mock exams I gained confidence and kept doing them over and over and I passed my test on st pattys day
This was a great help took the practice exams and then took my actual exam the next day and passed! He had a lot of questions that ended up being on the exam but just worded differently.
I bought the CER practice test the day before my exam. I didn’t know what to expect but surprisingly the practice test covered the same material that’s on the CER exam. Honestly if I didn’t buy the practice test I wouldn’t have passed. Thanks to The Sterile Guy I’m CER certified!
Such a great way to get yourself ready for the CIS exam. I used these practice test and was able to pass the exam on the first try. Thank you On to CHL next.
I am still studying to take the exam! So far I love the materials. I am taking my time studying but I can’t wait to take it soon just so I can see if the study guide here are helpful for the exam. I will leave another review after I take the exam soon.
This bundle I bought is very helpful and is definitely helping me prepare for the test. I just keep retake the practice exam until I know I’m ready but definitely one of the best practices test and bundle out here.
Passed the exam and got certified as CHL after reviewing your course for a week ... I got some 20 to 22 questions from your content in the exam out of 150 questions... not bad ...
