External Resources for Chemistry 3/4?

Hi I was just wondering is it worth buying and using NEAP SmartStudy Questions and Exams, A+ Notes and Exams, Checkpoints, Exampro, etc..? My school does provide practice exams but in terms of SACS and more practice exams/questions, but which ones are the "best/most useful"?

[I apologise in advance if this type of question has been asked before and thank you for your responses ^^]

[and yes, i've asked the same question for methods, specialist and chemistry...]

I think Checkpoints is good because it separates VCAA questions into topics so it's easier to work through during the year. However, if you are on a tight budget / don't want to buy every book, you could skip this as it is possible (although time consuming) to go through the exams and do the relevant questions. Keep in mind that some schools/teachers will make you work from checkpoints during the year, so check with them first.
I used NEAP questions but not exams. NEAP is generally quite difficult so it's good to extend yourself if you are looking for those top marks. I mainly used it to prepare for SACs as my school had a pretty high standard for coursework. By the end of the year I mainly did VCAA and company papers, so I ended up doing NEAP papers (provided by the school) instead of doing the NEAP exam book.
I never used A+ exams for chemistry, had it for methods and never really liked it. Have a look at the book and come up with a decision for that. I just didn't think it was very VCAA like. On the other hand, A+ notes are pretty good, especially if your teacher's notes are not that organised/detailed. They are just a summary though, so you might have to look to the textbook/notes online to completely understand a piece of theory though. Keep in mind before you decide to buy them that there are plenty of notes online that you could use instead.
Exampro (especially chem) is amazing. It's very difficult and is definitely targeted at top students, but the explanations are gold and give a much better and deeper understanding of the course. That being said, it is expensive - so only buy it if you are willing to push yourself.
