+<h1>IELTS Success Stories Analysis and Prediction Model</h1>
+
+**GOAL**
+
+The aim of this project is to analyze and predict the success rates of IELTS.
+
+**DATASET**
+
+https://www.kaggle.com/datasets/zakirkhanaleemi/ielts-success-stories-dataset
+
+**DESCRIPTION**
+
+To analyze the IELTS Success Stories Dataset and build and train the model on the basis of different features and variables.
+
+
+### Visualization and EDA of different attributes:

+
+
+**MODELS USED**
+
+| Model                       | MSE_train           | R2_train | MSE_test  | R2_test   |

+
+**WHAT I HAD DONE**
+
+* Load the dataset which contains 27 entries in it and having 23 features in it.
+* Checked for missing values and cleaned the data accordingly.
+* Analyzed the data, found insights and visualized them accordingly.
+* Plotting heatmap using correlation and checking the relation between different features.
+* Found detailed insights of different columns with target variable using plotting libraries and plot the box-plot to see the distribution of dataset correspond to target features.
+* Split the dataset into training and testing dataset.
+* Apply PCA to reduce the number of features.
+* Apply different training models and get their accuracies and MSE and R2 scores.
+* Train the datasets by different models and saves their accuracies into a dataframe.
+
+
+**LIBRARIES NEEDED**
+
+1. Pandas
+2. Matplotlib
+3. Sklearn
+4. NumPy
+5. XGBoost
+6. Tensorflow
+7. Keras
+8. Sci-py
+9. Seaborn
+
+
+**CONCLUSION**
+
+- Random Forest and XG Boost Regression models show promising performance with lower MSE and higher R2 values.
+- Decision Tree Regression achieved perfect R2 on the training set but performed poorly on the test set, indicating overfitting.
