Improving Speed

Hi everyone! I was wondering if anyone has recommendations for where to find full section practice of difficult quant sections? I do really well during the first quant section and then always end up freaking out during the second quant section because of time. Looking back, the questions I get wrong on quant aren’t because I couldn’t solve it, I just didn’t have enough time.

Any tips to improve speed and also where to find full 20 set questions to practice the hard quant section?
