How do I prepare for the 1st-semester RGPV exams?

If you are a profound student who wants to do something worthwhile after finishing your engineering degree, you must first master the fundamentals. Following that, you must read good books or references on the subject. You can also watch online video lectures on YouTube. You should have good logical thinking and imagination for Engineering Drawing.

You should not rely solely on YouTube; instead, look into other options such as reading books, magazines, and so on. The most important requirement is self-study. Aside from watching YouTube lectures or making Notes & Assignments, you'll need to devote enough time to a specific subject. 

Concentrate intently on your desired outcome. You must have a strong command of the English language, excellent communication skills, and software skills in C, C++, Java, JavaScript, and Python.

Aside from that, focus on Aptitude and Reasoning from the start; it will help you in the coming years when you will be facing campus. If you are a civil or mechanical engineering student, you must be proficient in software such as AutoCAD, CATIA, and others.

You simply need to create a clear strategy from the first semester onwards and focus on each of these things, and you will gain the advantages sooner or later.
