If you study hard, you succeed. (Correct the following sentence)

The original sentence "If you study hard, you succeed" is grammatically correct as a Zero Conditional, which describes general truths or facts. For example, "If you heat water, it boils."

However, given the topic "First Conditional," the intention is likely to express a real possibility or probable outcome in the future. The First Conditional structure is:

    
• If + Simple Present, Will + Base Form of Verb

In this structure, the 'if' clause describes a condition, and the main clause describes the likely result if that condition is met. Therefore, to align with the First Conditional structure, the main clause needs 'will' + base verb.
