Hello.

To prepare for Polytechnic first of all you should be familiar with the syllabus of that examination. Syllabus is almost same for all polytechnic entrance examination, you might download or see from any previous year question Bank.

First of all clear you basic from NCERT of class 9 and 10(Mathematics and science).

After that solve previous year paper of the university for polytechnic you wish to appear.

Previous year question Bank is easily available in any bookstore. Solve it religiously because some of the questions are always repeated from this.

One thing you should know the syllabus of polytechnic entrance is different in various States But in mathematic and science mostly topics are common.

I am going to list 5 tips to cracks the entrance exam.

1. Go through the text book (ncert etc) and make a short note if possible.
2. You can refer any STUDY GUIDE related to your entrance.
3. Do the past 5 year question because 20-30% will be from these.
4. Just focus on basic formula or CONCEPT and make a mind map.
5. practice more and more to get speed and accuracy.

Hope this is helpful.

Good luck.
