Hello,

I would like to tell you that your attendance plays a small role and rather you being able to do the practical at the time of final pracs are more important.

You need to attend the pracs and learn what is going on, how is it happening as it becomes really hectic as people pass in theory papers but fail in pracs.

I would also suggest you to practice the practicals few days before the exams if the lab is free and do keep good relations with your teacher as it may help you. 

Hope this helps and all the very best!
