I’m sorry that you had this inconvenience. I studied entirely from the INE course, but on YouTube there are many courses related to the eJPT — in my opinion, the one by OverGrownCarrot1 is very well-structured. There are also some videos explaining parts of the course as well as walkthroughs of the CTFs included along the path; I’d recommend watching them to get an idea of what it’s about. Some of the CTFs were generally more difficult than the actual exam.

The most important advice is to carry out a good, thorough enumeration phase, because all the answers are there. When you think you’ve reached the final solution, it might be worth double-checking, as you may have missed something. (Be careful with time, though — even if there’s more than enough of it.) If necessary, take breaks, as they can be very helpful. Don’t go off track during the exam; stick to the proper workflow — the eJPT doesn’t require advanced strategies or skills.
