Decent but not great

Alright,
In my experience I found gmatclub tests to be good but not great. The reason? Its more quant oriented. If you want unlimited supply of tough quant questions, gmatclub is an amazing resource. Though I didn't it extensively as I already scored a Q51 in quant!
My pain area was verbal and I found it OK. Its good for practise sake but it could have been better. Explanations sometimes keep asking me for more. May be because I'm relatively weak in Verbal. Anyways, I would recommend gmatclub Quant for any1 who is absolutely through with the basics and is looking for some good quality practise. Getting Q50-51 in quant is very much possible if you practise enough and gmatclub is a great resource. For verbal don't consider gmatclub as a primary resource though its good for additional practise.
