I studied by reading the entire book once and then answering all the questions in the app.
I practiced so much that I was able to pass 10 mock exams of 70 questions — they felt easy.
Here’s the thing: after reading and practicing a lot, you definitely learn and understand the concepts. But in the actual exam, the questions are different, so my experience was quite stressful. First in the exam, I had to read the questions carefully, understand them, and think hard about the answers.
What felt easy in the simulations was actually quite difficult in real life. I had to concentrate as much as possible and managed to finish the 70 questions just in time. I only had time to review about 20 questions for second time — there wasn’t time for more.
Luckily, I passed by just 3 questions, but it was definitely demanding.
So, I recommend reading the book — but take your time and really understand it.
Practice the questions using the app, and whenever you get one wrong, read the explanation carefully to understand why.
Keep practicing mock exams until you can do them almost automatically.
This doesn’t guarantee you’ll pass the real exam — because it was tough for me — but it definitely helps a lot.
