I have subscribed for the Club tests mainly for Quants section. If you are into final stage of your preparation then this test is very good to opt for and worth money and time. Best time to buy it is with 50 pc cut while you are using the full membership during US bank holidays.
If you are looking to start your preparation then this may not be the best option as this will might not help you in understanding some of the things. Reviews, scorecards, trackers all are wondefull and very full to keep a track of your preps. Must buy for if you are aiming for very good score in Quants.
