我想继续这样学下去

If I want to follow the word order in your original sentence but don't want the translation sound too English-like, I would probably say, "我想繼續(像)這樣學下去". 我 = I 想 = would like to 繼續 = continue (像)這樣學下去 = studying like this To translate the "verb + like this/that" structure in English into Chinese without sounding awkward, you want to reverse it into "like this/that (像這樣/那樣)+ verb". On top of that, it will actually sound more natural to drop the word like, or 像。 The "繼續 + verb + 下去" structure is a very common one in Chinese. The 下去 part has the sense of "all the way", so it's your call whether or not you want to drop it. If you definitely want to include 再, you can put it in front of 繼續 or 這樣。
