I have roughly 3 weeks left before my test. I completed the quant foundations course (I’m Overwhelmed) and I have the ETS power prep pack books as well as the Manhattan 5 lb book for quant. Because I have just three weeks left to go, should I use just the ETS books moving forward for untimed & timed practice? Or do you still recommend I use the Big Book for untimed and timed practice? I’m focusing untimed practice on areas of weakness. How could I/should I use the Manhattan 5 lb pound book at all during this time? Any guidance would be much appreciated. Thanks!
