Yes, you can do that if you only care about points. If you want to actually learn the verses, however, it will hurt you the more you do it. The way spaced repetition works is that it will show you the verse again based upon how well you got it right. If you reload the verse until you get it perfect, the program will think you got it right and increase the time interval. Before you know it, your interval will be at several weeks, and you'll have to keep refreshing it to keep up. It is better to go ahead and miss the words, or use the hints to help you remember. Points are fun, and seeing your name pop up is exciting, but the more important thing is that you come away from this website knowing the verses you are practicing so they can change your life. These achievements mean nothing compared to that. As a side note, there are times where I refresh a verse, like when I accidentally fat fingered the wrong key, or if the website gets confused and thinks I missed it when I didn't.
