I believe Edrolo covers most-if-not-all topics in the course, as they are approved by the VCAA, however, I do agree that they are a bit shallow. I think Edrolo is better as a preliminary or revision course, not really something to rely on when properly consolidating the minutiae of the information.
The Jacaranda textbook is far superior in terms of information, and nearly everything you need to know is there, but, as is with most textbooks, a lot of information needs to be sifted down. I personally sift through information in the textbook and paraphrased information in class to make study notes consisting of just a document with topic names and dot points. The learning activities in the textbook I feel are reasonable material for applying the information just learned and it does help with SACs and exams.
INSIDE SCHOOL
My personal extra recommendations for taking notes in Psych is to always have your laptop open or a book open when your teacher is explaining something. Get into the habit of picking out useful information from their mini-lectures and jot it down, especially if it's new information. Then, take their explanation and find the relevant area in the textbook or other resources if their explanation was brief and/or unsatisfying, also just to cross-check that they explained it adequately.
I'd assume that your school would give you some sort of checklist or something before the test or exam, which should provide a rough guide for what you need to study for. By the time they give you such a checklist, your notes should have most of the information required, and you can brush back up on your resources to further prune or add information.
OUTSIDE SCHOOL
I also use the study guide on Sparknotes.com and copy down notes from there, which although does stray from VCE quite a lot (since it's not made directly for VCE), it does provide extra explanations in different wording and should allow you to get a grasp on how psychology functions as a tertiary study. There's a lot of new concepts that you won't cover in school there, so if you're keen for extension, go for it.
Videos on YouTube from channels such as CrashCourse and Vsauce are also excellent resources for learning, and I would recommend them as study material too.
I also find that reading other papers relating to psychology quite fun, especially if they're in the form of an experimenter's notes. When trying to understand how they conducted the experiment and also scrutinizing their methods and results, it really does serve as extra practice for the research methods part of the subject. When you can, do a quick Google search for a psychological test, or some crazy bastard who decided to go for a mall shooting, and analyse what led them to make that decision. What was the reason behind the action or reaction? How did you come to that conclusion?
Really, in conclusion, the Jacaranda textbook is superior in terms of hardcore studying information for this subject, but Edrolo is still useful as a secondary resource for preliminary or revision material. Taking notes in psych classes need to be disciplined and thorough, and you must find what information in pertinent to what you're studying when the teacher gives lectures. To further yourself, doing extra study outside of the VCE programme is quite invigorating, since it keeps your mind interested in the topic itself, rather than the regimented school subject.
Hope this helps.
