This is a summary of ISTQB-CTFL-AuT syllabus version 2.0.2. I wrote it during my preparation period for the exam. I suggest reading the whole syllabus first or going through a playlist that explains the content then using this as a review. This is based on the learning objectives that are covered in the exam and is not a substitute for the original document. I recommend going through the syllabus in full and then referring to this document as a review. The ISTQB-CTFL file is incomplete and was just put in to fill on some prerequisite knowledge needed for ISTQB-CTFL-AuT. There are no plans to summerise them till now. I have an old highlighted PDF file for ISTQB-CTFL for version v3.1.1 and for CTFL-AT version 1.0. You can find these files along with ISTQB-CTFL-AuT here.
For a better reading experience rendering the callouts and reference linking I suggest viewing this on Obsidian. You need to view ISTQB-CTFL-AuT only as the other files are linked to it with context.
Please let me know if there are any mistakes that I should correct. I hope that you will find this helpful. I wish you all the best in your exam.
