IMO-B
Twice as (much/many/X) as is correct idiom.
in this case X:fast

IMO B

i think "what it was in" sounds awkward.

IMO C
the rate is not "fast"
for ex:
plane is twice as fast as bullet train
NOT that "speed of plane is twice is fast as speed of bullet train"

The powers of two are bloody impolite!!

Agree with above.

C is correct.

if the rate is twice , it is obviously fast. Fast adds redundancy.

Yes the correct answer is C, but I am still not convinced by your reasons.

The OE says both are grammatically correct, so reject B for wordiness.

However, as pointed above

think "what it was in" sounds awkward.

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score.

TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
