Clarification on income from tution

Dear Sirs,

I am filling ITR1 and show the income from Tutions that I take under PART B GROSS TOTAL INCOME ,  B3 under "Any other" . I would like to know if i can show any expenses incurred due to taking tuitions like printing the materials for taking tutions , travel expense to travel to tution center to reduce my overall taxable income. 

i don't own the class , I just get paid for per hour class and it is not a consistent monthyl income as this is handwriting improvement classes for students and if there are enough students then i get called to take class. 

regards

kv
