I haven't given bitsat session 1 in all bitsat mocks on embibe 4 I have given till now I am getting 130-140. But it's not even near cutoff. I try analysing question but due to incomplete syllabus even analysis one subject takes a whole day. What to do in these last 20 days. I am jee dropper I studied all chapters in detail during coaching. I have around 50+ copies I solved during prep time. Got distracted 3 months before jee mains attempt 1 got 81 percentile became serious a little got 89 in april in 2025 decided to take a drop for 2026. I got more and more distracted during drop year got 73 and 81 percentile this year. I have forgotten everything I had studied earlier. Some question I just still remember somehow that helps me score....

How to improve my score 🥲 just 20 days left even less 2 days for travelling another city

Hii guys ,

PORTFOLIO: "this is my first project and I do not have a portfolio of any kind". I am a 12th passed student going to join college this or next year for btech

It's a simplest version of the game opticgun based on the physics of ray optics mirror formula.

Problem - physics aspirants dealing with sign problems in mirror formula application.

Solution - a toy gun based on the formula.

Main target/ small adding updates in future - lens formulas challenge based games and more type of mirrors(ex ÷ plano convex) . A prototype for a real toy that will be made in future.

Design - A pistol like gun. The holding area had a calculator-like screen. The screen is attached to the typing pad containing numbers 0 to 9 , + , - sign button and an erase and input button.

The upper body of the gun has an empty circular slot for only one plastic copy of concave or convex mirror.

Only one out of two plastic copies containing two different resistors with a metal pin coming out from both sides can be fitted in it. Connecting it with the two metal pins inside the gun. The lower gun part is connected at the upper body through the same circular hole. It contains a solenoid which throws the plastic resistor out of the slot when required.

Working - hold the gun in hand fit the resistor plastic copy of the mirror. It passes through a circuit containing a voltmeter. The voltmeter gives information of the collected voltage.

The code is designed to work for only two given input voltage with a + , - 0.5 margin of error. The given voltage tells about the type of mirror. The code randomly chooses from the set of + or - ve numbers based on the type of mirror (voltage data) . The screen displays one focal length and one object distance from the 20 given inputs. If input matched the calculation done by it from the mirror formula it activates the solenoid to throw the resistor out and shoot the plastic bullet. No margin of errors in answer if wrong( in sign or number). It shows try again and nothing happens.

The simplest version I can think of for now

I have all 20 values of focal length and object distance with the answer of image inputs. You just have to code for the instructions I have. Based on a single formula and simple coding. (I don't know how to code by the way). all the math part is done.

Have a good day thank you. If interested can dm

For - beginners and intermediate
