Title: Questions on the Extra Test
Post by: KV4PL on June 27, 2013, 08:59:35 AM
I took and passed the Tech and General test, they were pretty easy. I read the "A No-Nonsense Amateur Study Guide" for the Tech and General which were free, read them 3-4 times, took the tests here on eham.net until I was getting 90% each time. My question is I've been studying for the extra test and that is quite a bit more difficult than the first 2. There are some very large formulas with square roots and sine calculations. Are there a lot of questions that would have to be calculated on the test? They are in the question pool. I can't imagine remembering any of these formula's that are in the study guide.  Math is not one of my strong points

A good amount will required some calculating but not an overwhelming amount. I used hamtestonline.com to study. I used their program for about 15 hours and I passed. Notice I didnt say aced it. They normally recommend 30 hours of study. The Extra test was the hardest thing I have done since college.

I passed the extra last Saturday, just before Field Day kicked off.  I got lucky, the only math question on the test was about the peak to peek voltage of household 120v RMS. No calculator needed. After studying using Hamtest Online (a great resourse) for 14 hours, I passed the Extra with a 94%. Not all that hard.

Just like the other tests, the Extra test is composed of a certain number of questions from each category within the pool. If math isn't your strong suit, it is not a total disaster as long as you can offset that by doing well in other categories that are less math intensive to make up for it.

Good luck!

I've been studying for the same exam.  It turns out that most of the questions that appear at first glance to require formulas and complex math can be answered by remembering a few 'rules of thumb' and estimating.  There will be only one answer that is close to your estimate.

For example, there are several questions that look like they require you to do rectangular-to-polar conversion.  For example, Question E5B08:

"What is the phase angle between the voltage across and current though a series RLC circuit if Xc is 100 ohms, R is 100 ohms, and Xl is 75 ohms."

I have observed that in every one of these questions the numerical value of the angle is always 14 degrees. Then just remember the ELI the ICE man rule to determine if voltage leads current or vise versa.

Personally, I didn't think any of the 3 Amateur test were particularly hard; I was lucky to have written a 100% on all three of them.  For the Technician test, I read over the Question/Answer Pool 3 times then sat for the exam.  About 6 weeks later, I enrolled in the Ham Test Online for the General and Extra tests.

For the Extra exam, I spent 4 days using the software to study the questions and their answers.  Then the next week, I spent 3 days taking the online test that Ham Test Online provided then sat for the Extra Exam and was lucky enough to have written a 100% on it.  When it came to the mathematical questions, being a retired Mathematician, I reduced the formulas to their simplest form and learned to use the "numbers" given in the question and plugged them into the resultant formulas to answer the questions.  Some of the math questions have more information in them than is needed to answer the questions correctly.

I think the repetition used by the software does help in learning the content of the questions and the answers they expect you to give as an answer.  At least, it worked for me on two occasions.

Good luck on your study and sitting for the Extra Ticket.

Here is a youtube video that is an example of what I was saying in an earlier post. Solving what looks like a complex exam question using a rule of thumb:

Here is another example of an exam question that can be solved vis rule of thumb instead of complex calculations:

E5C22: In rectangular coordinates, what is the impedance of a network consisting of a 10-microhenry inductor in series with a 40-ohm resistor at 500 MHz?

A. 40 + j31,400
B. 40 - j31,400
C. 31,400 + j40
D. 31,400 - j40

Since we know that the resistance is the number on the left and reactance is on the right we immediately know the answer has to be A or B.

All we have to do is remember that inductance is positive and capacitance is negative to determine that the answer is A.

I'm also studying for the Extra exam, and like someone said, I scored 100% on both the Technician and General - but I doubt that will happen on the Extra exam.  I am very good at working out numbers in my head, and if you give me a formula, I can work out the answer, but when it comes to remembering formulas, I suck!  All my life, I was raised with the idea that most formulas didn't need to be memorized because like any other form of reference, you could look them up.  In fact, many of my geometry and trig classes either let us look up the formulas in our book, or gave them to us (but it was always up to us to figure out which one was the right one to use).  This was even in college.

This will be a challenge!

Have you noticed that hamtestonline is a common thread here?  I highly recommend using it. 

Also, don't sweat the math.  Study it but don't sweat it.  You can miss all the problems that involve formulas and still pass the exam.

I also used hamtestonline, and passed my Extra exam. Hardest darn test I've ever taken in my life but I passed. Like others have said, don't sweat the math. Good luck!

I studied extra hard on the other sections to make up for any deficiencies in the math. Still, even if you aren't great in math, everything in the study guides is identical to what's on the test, so you can actually memorize questions and answers and not even have to work the math. I don't know if that works, because I was so excited when I passed that I didn't bother asking for my grade, lol.

If you spent time looking at all of the questions and took sample exams, you should be okay.

Thanks Chris, I've been hitting the practice tests after reading Dan Romanchick's "No-Nonsense Amateur Radio Study Guide" about 3 times, but it seems at 60 CRS seems to start setting in. lol

Well I did it. I dont know how many i missed, but it  must have been good enough.

Congratulations! 

As you long as you pass, it does not matter how many you miss.  The good thing is if you renew your license on time, you'll never have to take it again.

When I took my Tech and General (both passed) the VE's convinced me to try the Extra even though I had not studied the material... since it was "free" and I had the time, I took the test.  I was shocked that I only failed my 5 questions.  There were almost no pure math questions in my test.  There were some that required estimating and there may have been one that looked like I would need to calculate... but not that bad.

I am studying now and will take it again in Oct.  I am pretty confident I can pass judging by what I saw and my previous experience.  I am also using HamTestOnline as my primary source.  I really like the links to more info on given subjects.

I was actually counting on the math questions to make up for my abysmal knowledge of electronics - but as everyone has said, there aren't very many math questions - no differential equations, no calculus, and no complex arithmetic.

And even though I actually _like_ math, I used some of the tricks mentioned above to save time and avoid stupid misteaks...

I took the extra last night and passed fairly easily.  I remember 2 math questions. I was kind of bummed as I had expected more.  But when you look at the sections, many have no math so it can be the luck of the question pool.

Passed mine as well on Sat... and again, only a few math questions and if you can estimate, you can get those as well since it is multiple choice.  They make a couple of them odviously wrong and 2 close to the answer.  You can usually noodle out the correct answer without calculating anything.  That may be bad for a math wiz, but it worked well for my knowladge base.

On most of the tests including commercial it has been my experience that if you really understand the equation and what is going on, you won't even need the calculator.

Got my Tech and General a week apart this past Spring, passed the Extra exam today.  I studied Gordo's book for about 30min a day for 3 weeks, and also took the practice exams on QRZ.  Learning CW is my next thing to tackle!

I applied the rule of using minimal power to get the signal out and took the Extra test today with minimal time spent on learning. It paid off: passed with 74%. Not one millisecond wasted  ;)

That said, count me in with those who said this was the hardest test they ever took. Mechanical problems to solve? In my sleep. Building antennas? If you give me a plan, sure. But electronics? What's that? I will always only be a CW operator and never more in this hobby, but give me credit for striving to be good at it.

Happy Holidays!

Whether the tests are hard or not depends a lot on your background and preparation. I took the Tech and General in a single sitting and the followed that with the Advanced and Extra. Since my background was Engineering, none of them were very hard. But for the 13 and 20 WPM Morse tests you had to prepare. And I did.

Probably the hardest test I ever took was the final for Calc 4. There was only one problem, and we were given two weeks to solve it.

I hear you. If code were still a requirement, 20 WPM would have been very easy for me, since Navy radio op is my background  :)

Yeah, I know, they make it so easy for students now  :P
