I have joined Vision IAS test series for 2014 mains. Paid 20000 for GS + Optional. Question quality and checking standards (although checked by students only) are good. But the major issue is regarding time that they take to check papers. In the begining they took 7-10 days to check papers. Then almost 15 days. But now its been 20 days but no response from their side. Its really pathetic. First they overcharge (almost 1000 per paper) and then this kind of service.
Now they have started new test series. It won't be very helpful guys. I suggest you take papers from other aspirants & write at home. You can evaluate each other papers & also share cost. Even I am considering the same.
