SUBELEMENT G0 -- RF SAFETY [5 Exam Questions -- 5 Groups]
The rest just takes a quick read of the Part 97 reg (about an hour), this I have to memorize:
Frequency privileges for General Class  (ITU Region 2)
160M 1800 -  2000-kHz
80M   3525 -  3775-kHz and 3850 - 4000-kHz
40M 7025 -  7150-kHz and 7225 - 7300-kHz
30M 10100 - 10150-kHz
20M 14025 - 14150-kHz and 14225 - 14350-kHz 
17M 18068 - 18168-kHz  
15M 21025 - 21200-kHz and 21300 - 21450-kHz
12M 24890 - 24990-kHz
10M 28000 - 29700-kHz

3690 kHz - 200 watts PEP output
10.140 MHz - 200 watts PEP output
Answer to all other power ?s in pool except 60M is 1500W
5 freqs in the 60m band reg represents a disproportionate # of questions  (3) in the pool, emphasis on key pts:
97.303(s) An amateur station having an operator holding a General, Advanced or Amateur Extra Class license may only transmit single sideband, suppressed carrier, (emission type 2K8J3E) upper sideband on the channels 5332 kHz, 5348 kHz, 5368 kHz, 5373 kHz, and 5405 kHz. Amateur stations shall ensure that their transmission occupies only the 2.8 kHz centered around each of these frequencies. Transmissions shall not exceed an effective radiated power (e.r.p.) of 50 W PEP. For the purpose of computing e.r.p. the transmitter PEP will be multiplied with the antenna gain relative to a dipole or equivalent calculation in decibels. A half wave dipole antenna will be presumed to have a gain of 0 dBd. Licenses using other antennas must maintain in their records either the manufacturer data on the antenna gain or calculations of the antenna gain. No amateur station may cause harmful interference to stations authorized in the mobile and fixed services; nor is any amateur station protected from interference due to the operation of any such station.
SUBELEMENT G1 -- COMMISSION'S RULES [6 Exam Questions -- Got to know some of these]

Antenna towers 200ft max, "space shuttle retransmission" is the exception to everything.
FCC doesn't want hams making CB amps for fun and profit: 1 a yr below 144M, if cert reqd, can't be used 28-35mhz.
General can only prep and administer element 1 or 2 exams, with proper VE accreditation.
SUBELEMENT G2 -- OPERATING PROCEDURES [6 Exam Questions -- Got to know some of these, mostly common sense]
G2A/B - Be nice.
G2C - Break any rule you need to in an emergency.
G2D - old fart police (FCC CIB), if there's a problem, point the beam someplace else, log your qsos.
G2E what is ITU? ITU Regions 1 emea, 2 americas 3 asiapacific, inordinate number of simple VOX questions
G2F trick qs are RTTY baud rates: 300 below 10M, 1200 at 10M (1khz bandwidth), 19.4K at 6-2M, 56K 1.25M up (20khz bandwidth)
SUBELEMENT G3 -- RADIO WAVE PROPAGATION [3 Exam Questions -- don't really need this]
G3A Ionospheric disturbances; sunspots and solar radiation - wing it.
G3B Maximum usable frequency; propagation "hops" -- G3B05 trick q careful of "below" maximum
G3C F2 goes up at midday, summer. Scatter happens.
SUBELEMENT G4 -- AMATEUR RADIO PRACTICES [5 Exam Questions -- need some of these]
A lot of this is basic. Exceptions:
G4A Two-tone test: oscilloscope, any 2 harmonically unrelated audio tones.
G4D wire sizes and fuses (12 ga 20 amp house wiring)
SUBELEMENT G5 -- ELECTRICAL PRINCIPLES [2 Exam Questions -- wing it]
Calc TIP: transformer voltage::coil ratio, impeadence::sqroot(coil ratio)
SUBELEMENT G6 -- CIRCUIT COMPONENTS [1 exam question - wing it]
Tip: adjacent coils ought to be at right angles to one another to reduce cross-inductance, wire wound resisters oughtn't be used in tuned LC circuits.

SUBELEMENT G7 -- PRACTICAL CIRCUITS [1 exam question - wing it]
use a 2x margin when rectifying AC

SUBELEMENT G8 -- SIGNALS AND EMISSIONS [2 Exam Questions -- wing it]

G8A AM; FM; single and double sideband and carrier; bandwidth; modulation envelope; deviation; overmodulation
G8B Frequency mixing; multiplication; bandwidths; HF data communications
SUBELEMENT G9 -- ANTENNAS AND FEED-LINES [4 Exam Questions -- Got to know some of these]
Calc tips:
G9A Yagi antennas - lengths of elements in feet are ~475/mhz
G9B Loop antennas - lengths of loop in feet are 1005/mhz/number of sizes (delta 3, quad 4).

SUBELEMENT G0 -- RF SAFETY [5 Exam Questions -- Got to get most of these right, but they're pretty basic.]
On the RF safety field strength questions, watch the units. mVolt/meter differences are directly proportionate, while mWatt/meter^2 differences vary as the the square of the distance.
Max RF absorption is in the 30mhz-300mhz (10m-1.2m) range. Absorption is frequency-related. Don't point microwaves at your eyeballs. Long ground wires are bad.
