Jeanne’s experiences taking the 1Z0-815 exam

I wasn’t as fast as Scott who took the exam two months ago (the day after it came out). I waited until I was done with “FIRST robotics season” and a vacation before thinking about taking the first half of the new Oracle Certified Professional: Java 11 Developer certification. I passed today with an 87%.I’ll be taking the second half in a number of months.

Jeanne vs Scott’s exam

A lot changed since Scott took the exam. I think he got a lot of experimental/unscored questions. The exam was still harder than the OCA 8. But it wasn’t insanely hard like he got. Key differences:

  • Scott had a lot of “pick 3 or 8” type questions. About 75% of the questions I got were pick one out of four or five choices. I got exactly 4 questions with seven choices. One was “pick 3 or 7” and three were “pick 1 of 7”. I got about 6 questions with 6 answers. Two were “pick 2 of 6” and the others were “pick 1 of 6”. I got about 12 “choose 2 or 5” questions.
  • I got 7 questions on modules. Which is what you’d expect statistically. Scott had a lot more but I think that was because the topic was new and Oracle was testing questions.

What is still harder

  • Overall, it is longer than the OCA 8. It took me 75 minutes to get through all the questions on the first pass. Then I spent 50 minutes reviewing (and memorizing). During that phase, I fixed one incorrect answer and changed a correct answer to an incorrect answer so it was a wash.
  • The scope is larger than the OCA 8 and the questions go deeper. This makes sense as this is a professional level exam.

What else was interesting?

  • The instructions say press control to cross out answers. This didn’t work. (I had this problem before so it might be my exam center.)
  • The exam results are supposed to be available within 30 minutes. I didn’t bring my phone to the exam center. When I got home, the email with the results was from “30” minutes ago. It took me a little over half an hour from when I ended the exam until I go home so he results were available fast!

How I studied

Even though I’m the author a study book, I find I still need to review. More so for part 2 of the exam, but it still helps for part 1 seeing the details.

  • Read our OCA 8 book
  • Re-read the basic parts of Manning’s Module System book. I was the tech development editor for this book and also helped with some of the finishing touches.
  • Do all questions in our OCA 8 book and K&B’s 8 book.
  • Do about half the questions in our Practice exam book for OCA 8 and the mock exam. (I ran out of time to do them all. This was mainly about practicing speed and confidence anyway. I do know the material.)
  • Did the official practice questions. (It would have been better if these were split between part 1 and part 2)

Listening to Free Music on a ChromeBook

My mother decide she’d like to listed to music on here Chromebook. Conveniently the new Chromebook has good speakers. The gotcha is that she has limited bandwidth at home.

Luckily, this is still possible via a “simple three step procedure”

Step 0 – pre-req

  • Go to Amazon Play on the Chromebook and download the Amazon music app
  • Right click the Amazon music app and pin it. That way it always shows up on the bottom
  • Login to the Amazon music app using the account with a Prime membership. Note this must be the actual account with a Prime membership. Not one you merely shared free shipping with. (Amazon allows up to 10 devices with access to the music on a single Prime account so they must be ok with families sharing)

Step 1 – pick Amazon Prime songs

  • Go to Amazon Digital Music
  • Search for what you are interested in
  • Filter by Amazon Prime on the left
  • This will give you a list of albums with at least one free prime song
  • Each one tells you how many songs are included with prime
  • Click on the albums you are interested in
  • Click “Add” and the icon turns into “Listen now”. This makes it accessible via the app

Step 2 – download to Chromebook while on free wifi

While my mother is bandwidth limited at home, she has free wifi in the lobby and at the library. So for this step:

  • Open Amazon Music on the chromebook
  • Go to My Music. I had tow wait about two minutes for the new songs to show up
  • For each song, click the three dot icon at right and choose Download

Step 3 – listen to music on Chromebook

  • Without being online, open Amazon Music
  • Choose “Offline Music”
  • Click “Shuffle all”
  • Click “play” on first song. Then they all play

Chromebook the third!

I bought my mother a Chromebook in 2012 and again in 2014. That one lasted longer and here we are five years later. It’s time to replace the Chromebook with her third one. Definitely a happy customer.

I went the Best Buy like the last two times. The number of Chromebooks on the market exploded! I think they had nine in the store. I went with the Acer Chromebook 15. It’s a basic machine with built in speakers. Like actual speakers, not embedded ones.

Comparing the stats from 5 years ago

My mother wants to listen to music now. This means I care about the hard drive now when I didn’t five years ago. Everything is better on this machine except the CPU. The computer is never CPU bound though so that seems ok

Setting up the Chromebook

  • The Chromebook was set to Sept 18th 1:00 on May 15th 10:21. Maybe that’s when it was built/packaged? It got fixed automatically when I connected to wifi
  • I chose “let’s go” on the welcome screen and connected to my home wifi.
  • I then got the ChromeOS terms page. For about a minute, it showed me a cert invalid page. Then the screen loaded with the terms. Weird.
  • I chose not to send data to Google and accepted the terms. (My mother is bandwidth constrained so don’t want to use up any helping Google.)
  • Signed in. My profile was automatic. Since I signed on as my mother, I got her giant accessibility cursor
  • I accepted Google Play/Google Drive since I want to use an app. I did not enable location services.
  • On settings
    • disabled Bluetooth
    • disabled sync for passwords/addresses/google pay
    • changed time zone to Pacific
    • turned off check if have payment methods saved
    • on site settings, disable microphone and camera
  • Installed Keep Awake browser extension
  • Covered camera
  • Right click desktop and choose “set wallpaper”. Choose light blue under solid colors
  • I tested the USB, HDMI headphones and that a Kensington security lock works with
  • I made a recovery disk. The procedure hasn’t changed
  • Finally, I deleted a bunch of apps (go to the circle icon in the lower left corner). Right click the app to uninstall. The “uninstall” button is blue and looks grayed out, but you can still click on it (I needed a mouse for this – deleting with the trackpad doesn’t work.) I deleted a lot of stuff because it’s less apps my mother won’t use. Which means less stuff that needs to download auto updates
