Calculus is one of the major subjects in BSCE. 
Let me share with you my experience in calculus subject this online class. But before I want to share a little bit of information about myself. Stem (strand) is the preparatory for aspiring Engineers it teach different forms of math and science topics such as Basic-Cal, Pre-Cal etc. Unfortunately i didn't took Stem Strand during my Seniorhigh shool days due to financial problem. 
So let's get back to the topic. It's been 4 weeks since Online class started and tbh out of all the units in BSCE, calculus for me is the most hard subject. It was really hard for me to understand the topics since I have only limited idea of it. 
But you know what, here's what I learned during those weeks. We all know that its hard but if we will try our very best to analyze the problem I know we can able to solve/answer it. 
"Wag mong tigilan na intindihin ang isang problema hanggat masabi mo sa sarili mo na –Ay madali lang naman pala" Keep on analyzing the problem until you got to know how to solve it. 
Wait until you tell yourself that it was just an easy problem, you just have to analyze it. 
You don't need to be good in Math in Engineering just have a will to learn and trust the process.
