Hey guys, i'm just booked my gre test it will be in 3 weeks and i'm around 160Q and 152V (based on The last Manhattan full lenght test). I've not a strong vocabulary cause i'm not a native speaker so i'm aiming to 155 in Verbal, however i have a quant background. Every time i do the quant part and then checked the answer and i do silly mistakes like reading mistakes or wasting uselessly time in question in which i could answer qicklier. So there are in general no more than 2/3 question in which i really struggle, the rest are avoidable mistakes. What can i do to increase my score to 165+ in the next 3 weeks, and practice to not do these kind of mistakes, aiming to 165+Q 155V?

Thanks a lot in advance
