I am not at all satisfied with the approach of Prep Experts. They guarantee the score improvement of 200 points but they only consider the official test given by you before the course and after the course is taken. If you didn't give any official test before the course started they can not evaluate your improvement. I was asking them to compare the Prep Expert test score in the first week of the course with the last week Prep Expert course test score, but they said 'No'. My son only improved 100+ score in that 6 weeks against their guarantee of 200 points improvement. Also after they write the test every week during the course there was no feedback on improvement areas. They never consult my son telling him where he needs to focus on. and their argument on this is they don't pay personal attention in group class, we need to buy private courses if we need that facility. Then what's the point in taking test every week during the course if they are not going to provide feedback. At least once during they course they should have discuss the gaps that students need to focus on. This is so waste of money, if I would have known that this kind of coaching is given then we would have learnt from various online videos available on internet. This expensive, valueless coaching was not needed at all. This is a very much commercial activity where there is no intention to deliver any service to student to improve their score and just a money making process. As you all can see its refund and return policies are mentioned as "Difficult". I am totally disappointed with the service of Prep Expert and would not recommend it to anyone and I am going to put my review everywhere in social media.
