Honestly speaking, I don't think there are any good GMAT prep courses in Singapore. I'd tried Icon+, thinking that it is the best available in Singapore. Unfortunately, it offers below par quality. At the time I'd attended Icon+, it did not have it's own mock tests and sneakishly created my account on Manhattan GMAT
for me and bought the 6 mock tests @ $39. before I signed up for the course, they kept saying that Icon+ has its own practice tests etc. Their class room materials and trainers are also below average. In short, please don't waste your money and time at Icon+ in Singapore. It's not worth it!
I recommend you try the online courses such as Manhattan GMAT
, Knewton... They offer great materials, recorded sessions, and live sessions. All their trainers are really good. These courses cost much less than courses (Icon+) in Singapore, but they are really worth your money and offer great value.
Best wishes and good luck with your prep!Posted from my mobile device
