Hi Zarina,
Based on the information you've provided I would expect that you'll be entitled to student finance for the period of study you want to undertake. Please be aware though that in order to give you a definite answer I would need to review the details of your account with us and the info on your previous study period.
It might therefore be a good idea to speak with a phone adviser on 0300 100 0607 who can check all of your account info and who can make sure that your previous OU application has definitely been cancelled off.
If you are entitled to full student finance for the course you'll be able to apply for a Tuition Fee Loan, Maintenance Loan, Maintenance Grant, Childcare Grant (if needed) and Parent Learning Allowance (an extra non-repayable amount to help with parental costs).
Hope this helps,
