**Dear Readers,**

As SSC CGL exam is coming near, many of candidates are studying very hard for this exam and want to crack this exam very seriously. Many of candidates understand this thing that

**QUANTITATIVE APTITUDE**Section plays a pivotal role in deciding the cut-off for candidates giving this exam especially the

**ADVANCED MATHS portion.**

**“Study Plan for Advanced Maths”**. According to this plan, we would be publishing daily quiz of Advanced maths portion from where we would cover a topic each in it and we would update it daily in SSCADDA WEBSITE. AND ALSO THIS STUDY PLAN IS NOT PARTICULARLY FOR SSC EXAM BUT ALSO USEFUL FOR OTHER GOVERNMENT EXAM.
