I wouldn’t recommend matrix or any of these generic tutoring centres for maths. I would say ngo and sons, dr du, or Kurt should be the best. I’m not sure about how to find the booklets tho. Some people on bos sell their resources after finishing hsc so that’s a thing to look out for.
ngo and sons (specialist) and Kurt have the best questions. Dr du is meh tbh. This is coming from a dr du a1 ext 1 student, I now go ngo specialist
