Good course, but I felt Wizako's material was a bit lacking when it comes to certain topics (like algebra, powers & roots, and integer properties) and a little off-the-mark when it comes to others (like inequalities, sequences, and functions). Their word problem material though is excellent. Also, the price of Wizako's quant plus verbal course is equivalent to the premium online course offered by
Magoosh (which I felt is a better choice if you're looking for a well-balanced course with better GMAT-like questions)
That said, Wizako's pro-student culture is commendable and they do not engage in false marketing like many other GMAT coaching centers. Would definitely recommend Wizako, but supplementary material from other companies (like
Magoosh) may be required.
