I think you'll have a long wait. The new group hasn't expressed an interest in creating a certification. And even if they did, they have a bunch of higher priorities.

Note: We can run more than one promo in a given week, so check for updates.

That's definitely a server problem. I recommend waiting until Monday to see if it is solved. And then contacting Sybex support. Please reply here if you have trouble finding how to do that.
The exam price went up from $95 US to $155 US. Still less expensive than the "real" OCA, but a big price jump.

If you are think of taking the Foundation exam, read my blog for why I think you shouldn't
Unstickying now that the old OCAJ/SCJA have their end of life announced.
The comment about reuse is for if you want to change the number of months. If you want to change 1 months to three, you don't have to change the method that takes a Period as a parameter. And that's good reuse.

This feels trivial because everything is in one class. But pretend it wasn't. If another developer/team wrote the method and gave it to you inside a jar file, it wouldn't be so easy to change the method insides.
The 50 question chapters with the single answer questions are meant to be easy. They are reinforcing your learning so you are more likely to increase your score on regular tests.

I recommend doing the six end of chapter review questions in the OCA book a bunch of times. As you do each one, say why the right answer is what it is. Ideally out loud. This will train your brain to look for the details likely to trip you up on the exam.
What does that term mean to you? It could be developing a specific part of the app. It could be developing servers. It could even be deploying to servers

Not to take the exam. But to get certified afterwards, yes. So essentially, yes.
Enthuware is good and only $10. Go for it!
It's unlikely that anyone here is familiar with the Microsoft certs so you are unlikely to get an answer. Sorry.
I'm sorry to hear that. You do have to pay to take the exam again.

When you re-study, make sure you can explain why every review question answer is correct.
Yes, this can be done in raw SQL. It's not particular efficient; doing a loop behind the scenes. But for small datasets, that is fine.

The nested query gets the games a player played. If there aren't any for that player/match combo, the outer query includes the data. The distinct is because the cartesian product of the outer query creates duplicate rows.
