Theory exam

Oh man! My theory exam is in 2 months time and i have only 2 practice papers which i have not even completed. Help, especially with all the extra school work since school started and tennis training, there is even lesser time for me to complete some more papers. i plan to finish at least 5 practice papers but with the little time i have left, i think it is quite impossible. i only started learning in november, so that is an even greater disadvantage - not enough practice. What is more irritating is that the exam date falls on the 1st day of the bio Tioman trip so i am not able to go.
