Ron,
Glad to hear you are trying for General.
I know you will absolutely love it when you finally complete Elements 1 & 3.
As for where you should be comfortable in taking the written test, you are there or real close. I was running in the 90% range on the QRZ tests when I took mine.
Are there some areas that you are unsure of? If so, let me know and maybe I can offer some help.
Have you read any books or just take the practice tests.
I got a copy of the ARRL General License manual to read along with the practice tests. It helped me with some of the electrical/electronic theory.
2M Guy mentioned the freq privileges for General.
That is something that I had some trouble with memorizing.
I have a Gordon West General book that has some tricks for remembering band edges. If you need to know them, let me know and I will type them down for you, not hard to remember.
Also, download this
freq chart and check out the general subbands. When you get your general ticket you will soon learn the subbands because you are using them 8)
When you are ready to learn code, let me know.
I might be able to hook up my code practice oscillator to my computer and we could practice via echolink.
But don't worry about code this moment, just get through the written test and then you can focus on code. I know you can do this and I know you will have so much fun when you get your HF privileges. For me, it suddenly breathed new life into the amateur hobby for me. I have had a lot of enjoyment from having access to freqs from 1.8 mhz through 450 mhz just with my FT-847. And through it all, I still operate the VHF/UHF bands as well as good ol' 11 meters, but I leave my DX'ing to the ham bands now...much easier than DX'ing on 11
