ELI-Data-Mining-Group/PELIC-dataset: PELIC v1.1

In version 1.1, there are two significant changes to the PELIC dataset and supplementary repositories:

1. test_scores.csv: After cleaning, there is now one unique test score for each anon_id/semester_id combination. In addition, PELIC_compiled.csv has been updated to include two new columns for semester and placement_test.
2. PELIC-spelling: In the accompanying PELIC-spelling repository, a validation has been added to demonstrate the accuracy of the automated spell-checked texts.
