Paying off installment RRSP loan, how will this affect my FICO score?

Hi, currently i am working really hard im improving my credit score. I have 3 credit cards and 1 RRSP installment loan. What strategy it is better to use in terms of paying off installment loan (i've had it for 5 months)? Will paying off this loan will look better on my credit or i just have to leave it as is and stick to monthly payments? Thank you
