Maths King Formula

This is a proof of Maths King Formula: STUDY = FAIL

STUDY = NO FAIL ...(1)

NO STUDY = FAIL ... (2)

Equation (1) + Equation (2):

STUDY + NO STUDY = NO FAIL + FAIL
STUDY + NO STUDY = FAIL + NO FAIL ... (Commutative Law)
STUDY(1 + NO) = FAIL(1 +NO) ... (Factorize "STUDY" and "FAIL")
STUDY = FAIL ... (Eliminate "1 + NO")

Hence, STUDY = FAIL. (Proved)

My personal experience:
Initially, I was not so believed this 'formula' is true during I was in secondary school and upper secondary. This is because I studied hard and scored quite well that time. However, this formula is a reality when I stepped into university. I continued my study method that I used previously even during this university life. Sadly, it doesn't work. Recently, I studied the learning module, practiced tutorials in it and paid attention to lecture but yet I failed one of the test. I cannot believed too much on the module too because there are many typing errors and silly mistakes. The thing I wonder the most is that is the facts included in the module are accurate or not. From my point of view, is that formula should be restricted as:

STUDY + TIPS = NO FAIL;

Can anyone give me his/her opinion regarding the 'formula' and this restriction?
