Exams in education are based on critical thinking as well as current scholarship.
You can actually say what you like when it comes to the intepretation of evidence, as long as you are able to support your case with evidence - even if the examiner disagrees with you. What's being examined is your awareness of the debate, the issues involved, and how you make your own case. So you could argue that there was a revolution in government in mid-16th century England. Most scholars would now disagree with that, but if you in your exam essay argued that reasonably, citing relevant sources and facts, you could still in theory walk out with an 'A'. Deny that the holocaust happened, and in theory it's still possible to get your 'A' - but extremely unlikely because most the evidence is so overwhelming that you'd make factual errors or misuse sources or miss out critical evidence or arguments or whole works by other scholars, etc.
When scholarly books and journal articles are written, they go through a process of peer review by other experts in the field. Conspiracy theorists, holocaust deniers and creationists and their ilk will tell you that that's how alternative views of x [insert subject here] are blocked, but anyone who knows anything about academia will tell you that anything written must be with verifiable sources and/or - in the case of the sciences - experimental data that can be replicated in the lab. This written material is then read by
other scholars (obviously) and they're going to have something to say, so the process of checking and cross checking is continous.
There is no such checking process on the internet, and a lot of what passes for "information" on the internet turns out to be "misinformation", either on purpose or unknowingly. That's why you have to ask yourself, who's written this site and why, and what sources are they citing, and then acutally check those sources to see how scholarly they are. It's ok if they're not scholarly, but you enter at your own risk, so to speak. For example, one of the great internet myths is that the story of Jesus closely parallels that of Horus, an ancient Egyptian god, and it's one repeated on many sites, often without saying where this otherwise startling revelation comes from. The conclusion is that Christianity is a rip off from this particular ancient Egyptian mythical god. But in the end, there's only one source for that wheeze: an 18th century book long since discredited by scholars.
Personally, as far as the ancient Israelites are concerned, I'd go with scholarly books written for the general public over the internet, at least until I'd got a good background to figure out what's actually known and what's speculation. Personally, Finkelstein and Silberman's
The Bible Unearthed would be where I'd start. It's takes a sceptical view of the Bible (but one based on scholarship) in that it uses it as part of the evidence and not part of the intepretation of the evidence. It would, though, cite scholars who take different views to theirs that you could also follow up, and so on
