Here is a small periodic table that you can copy and make it in a hard paper or cartoon, so you can bring it everywhere and everyday. When you are free, spend a time to look at this table. Hopefully, day by day you can understand in dept the periodic properties of the important elements. I don't say that you must remember the symbol of elements. I mean, please think that the order of the elements both in a group and in a period, indicate a periodical properties, show the similarities and differences among the elements. All of these you have learnt in the X class this semester (first semester).You can make more than one copy, yeah ... it like a card, an ID card. Remember, this card is the key of chemistry.
