I had ordered the 3 set GMATFocus tests and yesterday i took the first test of the set. Here are my thoughts:
The first thing that comes to my mind is that it was tougher than the GMATPrep, and definitely tougher than most problems in OG11. Some of the problems that i encountered yesterday needed a lot of calculations. GMAT questions are supposed to be solved in less than 3 steps, but the answer explanations of some of the questions in GMATFocus involved 5 to 10 steps. For eg. one problem required to form 2 different equations, then apply a condition to one and then solve the equations to get the value for a variable and then substitute that in the eqn. to get the other value. It was easy but took me almost 160-180 secs. I got a question on Permutation and i had not reviewed this section at all.
The result is presented in a detailed fashion showing you your estimated scaled GMAT quant score, section-wise and topic-wise strike rate, time taken to solve right answers and wrong answers, number of them guessed etc etc. What i didn't like was their overall scaled score prediction. They predicted my score to be within 40 - 47 with 80% confidence. Well, i guess after completing all the three tests may be i'll get some insight to where i stand!!!
So overall the experience was good, and it was a very good practice of some new questions.
Verdict - Recommended.
