What are the best websites for bank exams preparation?

In April, my son began studying for the exams from the previous year. He is currently employed as a PO at the SBI Bank. When I asked him which website he follow, he recommended this one https://whitehillspublications.co.in when I visit this website. They offer point-by-point information and updated materials. To everyone, I would like to recommend this website. There is one thing missing from this website—a speed test portal—but they do offer offline PDFs for practise. Levels are comparable to exams. www.whitehillspublications.co.in
