If you're willing to pay then yes! Though bare in mind each paper costs money to be remarked (so if you wanted all papers remarked, you'd have to pay x3), so you need to decide how many of the 3 you want remarked and which ones you think you're most likely to get an extra mark in. Remarks are not cheap!
Definitely worth the remark though if you are willing to pay, I got all 3 of my OCR biology papers remarked last year (needed 4 more marks!) and went up 1 mark in one of the papers but down 1 mark in one of the others haha!
