GMAT Club Tests Review

I have been suscribe for GMAT Club Test for several months. Over all the GMAT Club test content is very good, especially for Quant that cover all the topic which are tested on the real gmat test. The design of GMAT Club test which similar to real GMAT test is good.

But I found several problem from side. Some technical problems, such as compatibility across browser, should be corrected. The GMAT Club test run fine on Firefox, but on Chrome I often find some problem such as :
1. while I pause the test, the timing is still running
2. some word/number format, such as dividen/power/function, often not appear properly.
For me who prefer using chrome to firefox for my daily activity would find this condition quite annoyed me because I have to open two browser anytime taking GMAT Club test.

With minor correction on several technical problems which mentioned aboved GMAT Club Test could be far better for subscriber.
